Kinetic Energy
A water bottle has the most kinetic energy at this point during a fall
What is the bottom?
At the top of a roller coaster, this energy is greatest.
What is gravitational potential energy?
The unit for kinetic energy
What is a joule (J)?
True or false: Potential energy is movement energy? If false tell us what type of energy it really is.
What is False and stored energy?
The ability to do work
What is energy?
The variable “m” stands for this
What is mass?
Why does an object have potential energy?
What is it is due to its position and its shape?
A 2 kg object moving at 3 m/s has this kinetic energy.
What is 9 J?
A stretched rubber band releases energy by converting elastic potential energy into this
What is kinetic energy?
A 2 kg object moving at 4 m/s has this kinetic energy.
What is 16 J?
If mass triples, gravitational potential energy does this
What is triples?
As a roller coaster reaches the top of a hill, this type of energy is at its maximum, while elastic potential energy would only be present if something were stretched or compressed.
What is gravitational potential energy?
Energy cannot be created or destroyed; this law explains it.
What is the law of conservation of energy?
An object moving at 8 m/s has 256 J of KE. Its mass is this.
What is 8 kg?
A roller coaster doubles its height. Its potential energy changes by this factor.
What is 2 times greater?
A moving object has 200 J of kinetic energy and is traveling at 10 m/s.
→ What is its mass?
mass= 4kg
An object has a mass of 4 kg and 196 J of gravitational potential energy. (g = 9.8 m/s²)
Solve for the height.
What is 5 meters?
Two objects fall from the same height, but one is heavier. They hit the ground with this difference in KE
What is the heavier object has more kinetic energy?
An object has 98 J of KE and a mass of 2 kg. Its velocity is this.
What is 9.9 m/s (≈10 m/s)?
Name the three types of potential energy.
What is elastic potential energy, gravitational potential energy, and chemical potential energy ?
