force
net force
inertia
gravity
What is inertia?
the force that opposes motion
the force of attraction between 2 objects

it has more mass
it has more volume
it is not as aerodynamic

An object has no net force acting on it. Which statement below best describes its motion?
It must be at rest.
It is either at rest or is moving with a constant velocity.
It is moving with a constant speed.
It is accelerating.
If a cannonball were launched into deep space (no friction or gravitational effects), how much force would be needed to keep the ball moving with a constant velocity?
A force equal to its weight.
No force would be needed.
A force large enough to balance friction.
150-N
You are riding in a car without wearing a seat belt and the car hits a tree and stops. Which of the reasons below best explains why you fly forward and hit the dashboard of the car?
There is no longer any force on the car. Since you were not wearing your seat belt the force is still on you pushing you forward until the dashboard cancelled it out.
Because the force was only applied to the car. Since you were not wearing your seat belt you continued moving forward until the dashboard stopped you.
The force was applied to the tree and to you since you were in the car. This force on you would actually cause you to fly out the back window of the car.
Since the car was stopped you were also stopped and would not have hit the dashboard.
