Golf Motion Project
Acceleration - a change in velocity over time 
-
The total distance can be found by calculating the total area between the graph and the starting point
P=mv (momentum=mass times velocity). Momentum and mass are directly proportional. momentum and velocity are also directly proportional. Mass and velocity are inversely proportional. This means that when momentum goes up, mass/velocity goes up. If mass goes up then velocity goes down. Directly proportional quantities are multiplied while inversely proportional quantities are divided.
Inversely proportionality graph

-
Velocity - speed and direction of an object's motion. Velocity is a vector quantity because it has more than one measurement of a quantity.

F=ma (force=mass times acceleration). Force and mass are directly proportional. Force and acceleration are also directly proportional. Mass and acceleration are inversely proportional. This means that when force goes up, mass/acceleration goes up. If mass goes up then acceleration goes down. Directly proportional quantities are multipled while inversely proportional quantities are divided.
Direct proportionality graph
-
Free-Body diagrams - diagram used to show the speed and direction of all the forces acting on an object in a specific question
-
Friction - the force that resists the motion of 2 objects in contact
-
Static Friction - friction between two non-moving objects. This is the strongest type of friction overall
Gravity - the force that causes objects to fall instead of staying up
-
Fluid Friction - friction that happens when an object moves through a liquid or gas. Air resistance is an example of this type of friction.
Speed - the distance traveled per unit of time. Speed= distance/time=m/s. Speed is a scalar quantity. A scalar quantity only has one measurement of a quanity.
Kinetic Friction - friction that is moving like rolling, sliding, and fluid. Rolling is the weakest while fluid is the strongest.
Static friction in golf - The golf ball starts as a non-moving object until the putter makes it go in the hole. Also, after you hit the ball and your ball is on the grass is another example of static friction.
Acceleration in golf - If you accelerate the club as it moves through each golf swing, you'll be going in the right direction with your game.
Reference direction in golf - If the path is moving in a very negative or positive direction, then the golfer needs a face angle to get the ball towards the hole.
Force in golf - You pull the golf club back and swing/push it towards the golf ball.
-
Gravity in golf - When you swing the golf club onto the golf ball, the ball goes into the air at a certain speed and eventually falls back down because of the gravitional force
Friction in golf - Golf has sliding, static, rolling, and fluid friction.
Sliding friction in golf - When the golfer is walking, that is an example of sliding friction because two objects slide over each other.
Reference point in golf - The reference point is a point that the player chooses that's on the course that is also on the reference line through the point where the ball last crosses the edge of the yellow penalty area.
Normal Force - the force that a surface pushes back up with
Instantaneous speed - the speed at a given time
Net force - the total of all the forces acting on an object. Formula: Fnet (net force of an object)=ma (mass multiplied by the object's acceleration)
Speed in golf - Professional golfers can usually reach a club head speed of 100 m/h at the bottom of their swing
Normal force in golf - When the ball is at rest on the tee or the ground there's normal force. When the golfer hits the ball, that force adds onto the normal force which makes the ball go in the air.
Velocity in golf - Professional golfers club heads can reach up to a peak velocity of 130 MPH when it first hits the ball
Rolling friction in golf - When you hit the ball and the ball keeps rolling until it stops it is an example of rolling friction.
Fluid friction in golf - If you hit your golf ball in water that's on the ground, it starts to cut through the water until it stops and this is an example of fluid friction. Also, when you hit the ball while it's in water, you aren't able to hit the ball as much because the fluid friction is slowing the club down.
Unbalanced forces - forces that aren't equal and opposite; causes a change in the motion of the object
Balanced forces - two forces acting in two opposite directions on an object and equal in size
Uniform motion - when an object has a velocity that stays in a straight line that remains the same.
-
-
Newton's First Law of Motion/The Law of Inertia - objects at rest stay at rest, and objects in motion stay in motion unless acted on by an unbalanced force.
Unbalanced forces in golf 2nd Law of Motion - When a golf club carries an unbalanced force it carries a change in velocity. The change in velocity equals acceleration which means that the greater the force applied to the ball the greater the acceleration.
Balanced forces in golf 1st Law of Motion - Balanced forces of gravity use downward and upward force of the ball and allows the ball to stay balanced on the tee.
Balanced forces in golf 2nd Law of Motion - When you hit the ball, it goes in the hole and creates a balanced force so the net force and dthe acceleration is zero.
Balanced forces in golf 3rd Law of Motion - As the club hits the ball it applies force which causes it to go in motion. This also applies an equal and opposite force back to the club. This makes the club slow down.
Unbalanced forces in golf 1st Law of Motion - When the golf club hits the ball there is an unbalanced force that makes the object (the golf ball) stay in non-uniform motion.
Unbalanced forces in golf 3rd Law of Motion - Unbalanced forces don't have an equal and opposite reaction, but if they did, when the golf club hits the ball the ball will be in uniform motion.
Uniform motion in golf 1st Law of Motion - When the ball is hit with the club while it's getting in the hole, it's technically going in a uniform circular motion.
Inertia in golf 1st Law of Motion - When the golf ball is on the tee there is inertia because the forces are balanced and the object stays in rest.
Rest in golf 1st Law of Motion - When the golf ball is on the tee there is rest because of the forces being balanced and having no movement.
Newton's Second Law of Motion - objects accelerate in the direction of the net force; the rate of acceleration is directly proportional to the size of the force and is inversely proportional to the mass of the object.
-
Motion in golf 2nd Law of Motion - The golf club applies more force to the golf ball than what the golf ball applies to the club. This causes the golf ball to move in the direction that the golf club hits it in.
Motion in Golf 3rd Law of Motion - When the golfer hits the ball off the tee with a certain force in a certain direction, then the ball will react back towards the club with the same force in the opposite direction.
-
Net force in golf - If the ball is hit in a certain direction then the net force will be in that direction because the force applied is greater than the force of the static friction. You can also find the net force in golf by multiplying the mass of the golf ball and the acceleration.
Friction in golf 2nd Law of Motion - Friction always acts in the direction opposing motion so if there's friction, some of the force from the golf club is lost causing the motion. This means the net force is reduced and the acceleration is smaller.
Equal and opposite reaction - a pair of forces acting on two objects that are equivalent
Equal and opposite reaction in golf third law of motion - When the club hits the ball it creates an equal and opposite direction. The club hits the ball with a certain force and the golf ball has the same amount of force in the opposite direction.
Momentum - a measure of how difficult it is to stop a moving object
Action in golf 3rd Law of Motion - When the golf club hits the ball on the tee, this is an action.
Law of Conservation of Momentum - the total momentum of a system remains the same before and after a collision
Law of Conservation of Momentum in golf - When the ball is hit, the momentum of the club is transferred to the ball instead of being lost.
Momentum in golf - When the ball is hit there's momentum, but when it's on the tee there's no momentum because it's at rest.
A distance time graph shows the motion of an object over a period of time while the velocity-time graph shows the speed of an object. Even when they're showing the same motions, they're going to look different.
