100

This is energy in motion.

What is kinetic

100

The distance of one full wave cycle

What is wavelength?

100

The flow of electrons through a wire.

What is current?

Solve for the following: a 1 kg beach ball going 4 m/s collides with a second 0.5 kg beach ball at rest. What is the velocity of the 0.5 kg beach ball after the collision if the 1 kg beach ball stops. 

What is 8 m/s

400

What must happens to force to create the same acceleration if mass increases by a factor of 4?

What is the force is quadrupled.

400

The total amount of energy in a system must remain constant.

What is conservation of energy?

400
When an object is moving towards you while also producing a sound wave this is what happens to the wavelength of the sound as it approaches you.

What is decreases?

400
Two charges that are 2 m apart has a force of 16 N.  The force that results when the same two charges are 4 m apart. 

What is 4N?

500

The total amount of momentum before a collision must equal the total amount of momentum after a collision.

What is conservation of momentum?

500

This is what happens if the force is held constant, but the mass of the object doubles.  

What is acceleration is cut in half.

500

An 2 kg object starts with 20 J of potential energy at the top of a hill.  As the object starts to go down the hill the PE is turned into KE.  What is the velocity of the object at the bottom of the hill?

What is 4.5 m/s?
