Which of the following forces can push (repel) and pull (attract)?
Magnetic Force
Gravitational Force

A basketball player shoots a free-throw. The motion of the basketball is shown. Describe the motion of the basketball after it leaves the player’s hands, and explain how this is an example of acceleration.
The ball travels in a curved trajectory in two directions with decreasing speed. This is acceleration because of the change in direction.
The ball moves downwards and then upwards in an arc. This is acceleration because of the change in force pulling the ball downwards.
The ball travels in a horizontal line to the basket with increasing speed. This is acceleration because of the change in velocity.
The ball travels in curved trajectory in a single direction with decreasing speed. This is acceleration because of the change in velocity.
Which graph best represents a graph of a car traveling forward on a freeway at a constant speed?
A
B
C
D

A F-16 fighter jet with a mass of 4000 Kg accelerates at 75 m/s/s.
What is the magnitude of force from the the jet’s engines needed to achieve this acceleration?
30,000 N
30 N
300,000 N
Two cars collide head-on. At every moment during the collision, the magnitude of the force the first car exerts on the second is exactly equal to the magnitude of the force the second car exerts on the first.
How is this collision an example of Newton’s 3rd Law of Motion?
After the collision, neither car has any velocity so no momentum is present. It would take an unbalanced force to make the cars move from the location.
We do not have enough information to determine the force of the impact as we do not know the mass or the acceleration of the cars before the collision.
Since the collision was equal and opposite, we can say that an equal force was exerted on both cars.

The magnitude of the force that the ball exerts on the bat is...?
5.0 N

larger
zero
the same
2. Which basketball has the most gravitational potential energy?
Basketball C has more gravitational potential energy because it has more mass.
Basketball B has the most energy because it is in the middle.
Basketball A has the most because it has the greatest height.
Basketball A has the most because it has the greatest mass.

What type of energy does pizza provide for us?
Pizza is chemical potential energy that is transformed to kinetic energy later on, as we move.
Pizza is gravitational potential because our body will digest it.
Pizza is elastic potential because the cheese stretches out of its normal position.
