Kinetic Energy
Will a moving ball at the bottom of a hill have more kinetic energy than a moving ball at the top of a hill starting at the same point?
What is a ball at the bottom of the hill?
Potential energy is in this state
What is stored
The collision where the object that is expected to break is moving first
What is Collision A
Will the object with more or less weight be affected more?
What is the object with the least weight
What factors go into gravitational potential energy
What is the object's weight and height from the ground?
What is kinetic energy
Kinetic energy is the energy an object has because of its motion and depends on its mass and speed
What is the unit of energy used for measuring it?
What is a joule?
A Head-On-Collision is?
What is two objects moving in opposite directions
In the class video of the cars crashing, did the cars get permanently damaged or temporarily?
What is temporary?
What is the further the object is stretched or compressed, the greater its potential energy is.
How many objects need to be moving in a collision
What is at least one
In collision B, which object has kinetic energy
What is the object that is not expected to break
Gravitational potential energy is?
What is the energy that is caused by the position of the object above Earth's surface?
The formula for kinetic energy
What is KE=1/2 mv^2
