Motion and Forces
Forces
2.1
A force is a push or a pull
Types of forces
Contact force
Gravity
Friction
Size and direction of forces
Balanced and unbalanced forces
Forces on moving objects
Newton's first law relates force and motion
Galileo's thought experiment
Newton's first law
Inertia
2.2
Newton's second law relates force, mass, and acceleration
Newton's second law
Force equals mass times acceleration
Force = mass * acceleration F = ma
Mass and acceleration
Forces can change the direction of motion
Centripetal force
Circular motion and Newton's second law
2.3
Newton's third law relates action and reaction forces
Action and reaction pairs
Action and reaction forces versus balanced forces
Newton's three laws describe and predict motion
2.4
Objects in motion have momentum
momentum = mass * velocity P = mv
Momentum can be transferred from one object to another
Momentum is conserved
Two types of collisions
Momentum and Newton's third law
Motion
1.1
Position describes the location of an object
Describing a position
Measuring distance
Motion is a change in position
Describing Motion
Relative motion
1.2
Position can change at difference rates
Calculating speed
Average speed
Distance - Time Graphs
Velocity includes speed and direction
Velocity
Vector - a quantity that has both size and direction
Velocity Versus Speed
1.3
Speed and direction can change with time
Acceleration can be calculated from velocity and time
Acceleration over time
Velocity - Time Graphs
Gravity, friction, and pressure
Masses attract each other
The force of gravity
