If a baseball has no velocity (v = 0), does this mean the acceleration is 0? Explain.
What is always g (9.8 m/s2) pointing down on Earth.

The diagram you draw to find the net force.
What is free-body diagram.

A ball is thrown straight up. Where in the ball's path is the PE the greatest? KE the greatest?
What is PE greatest at top, KE greatest right before hitting the ground.
200
Which one falls faster--a ball dropped or a ball thrown horizontally from the same height?
What is same--only vertical acceleration -9.8 m/s2.

What is orange.
300
What happens when your velocity and acceleration have different signs?
What is you slow down.
300
What does a net force of 0 mean (mention acceleration and velocity)?
What is acceleration is 0 meaning velocity isn't changing.

An ad for a toy ball once stated that it would rebound to a height greater than the height from which it was dropped. Is this possible? Explain.
What is no--conservation of mechanical energy.
300
In the roller-coaster lab, why were initial ME and final ME different?
What is friction.

How are free-fall motion and projectile motion related/different? Explain.
What is [discuss].

List Newton's 3 laws and describe.
What is inertia, Fnet=ma, action-reaction.
400
Can the speed of an object change if the net work done on it is zero?
What is yes - holding a box and walking horizontally.
400
One book vs. two books -- which one has more static friction?
What is two books--bigger mass.
400
Speed of light in vacuum.
What is 300,000,000 m/s.
500
List the 4 kinematics equations.
What is [on the board].

Explain why pushing down on a book as you push it across a table increases the force of friction between the table and the book.
What is Ffriction = mu * Fnormal. Increasing the normal force.

Furniture movers wish to load a truck using a ramp from the ground to the rear of the truck. One of the movers claims that less work would be required if the ramp's length were increased, reducing its angle with the horizontal. Is this claim valid? Explain.
What is no--force decreases but distance increases; remains constant.
