Forces
In our experiment
-
-
-
-
in each case, the force reading was the same on both sides
-
-
When the two objects interact, their force is always going to be the same
Newton's Third Law
For every force, there is always an equal an opposite force. When one object interacts with another object, its force will be the same size but the opposite direction as the other object's force
Both Newtonmeters will always have the same force reading no matter the situation ( even if one side pulls more
-
-
Normal force
-
Is always at a right angle to a surface ( wall, floor)
-
Name of Forces
-
-
Push
-
Push, the two objects need to be in contact
-
Forces 2.0
-
Unbalanced forces causes the object to move in the direction of the force. In this case, the velocity is changing
-
-
Newton's 1st Law
When an object experiences balanced forces, its velocity does not change. When an object experiences unbalanced forces it will experience a change in velocity ( also known as an acceleration)
Momentum
-
-
-
-
Example
If a 0.5 kg cart has a velocity of 3 m/s, its momentum is 0.5 kg x 3 m/s = 1.5 kg m/s
-

-
-
Constant Velocity
-
Slope
For every 1 second increase in time, the car changed its position by 0.5 m
-
Vertical- intercept
At time equals 0 seconds, the car is at position of 1m
-
Speed
How fast you're going, direction doesn't matter, scalar
Velocity
how fast you're going but the direction is important, vector
Observation
-
Second, heavier cart pushed the block farther
-
If the cart is heavier or if the cart was pushed harder, then the block would move farther.
-
Impulse
-
-
if the force is not constant, we simply integrate the force function over the set time period
the direction of the impulse vector will be direction of the force vector and the units will be a force times a time
