How come if you roll an ball on Earth, it eventually stops if Newton's 1st Law said it should remain in motion?
The ball will stop due to forces such as gravity and friction

If an apple and a piece of paper are dropped from a building on Earth, which will hit the ground first?
The apple will hit the ground first due to air resistance

John slammed his hand in his car door. How does this demonstrate Newton's 3rd Law?
The door had an equal and opposite force on the hand
200
By __________ the force, you can increase the acceleration
increasing

List an example of projectile motion
(answers may vary)
200
What is inertia?
The tendency of all objects to resist change in motion.
200
If an apple and a piece of paper are dropped from the moon, which will hit the ground first?
They will hit at the same time due to no air resistance.

How is a rocket taking off demonstrating Newton's 3rd Law?
In order to propel a rocket into outer space, it must have a strong push. The rocket is pushing on the ground with a strong force and the ground is pushing back, propelling it into outer space.

What are two ways you can increase the acceleration?
Increase the Force Decrease the mass

Gravity pulls the object down with an acceleration of ______ m/s/s.
9.8

How does hitting a golf ball demonstrate Newton's First Law?
The ball is sitting at rest on the tee. It gets hit by an unbalanced force (the golf club) and the object is put into motion.
300
List two ways to increase acceleration:
1) Decrease the mass 2) Increase the force

What is a property of a moving object that depends on the object's mass and velocity?
Momentum
