Energy is measured in:
Joules
An airplane, a car, and a bicycle are all traveling at the same velocity.
Which has the most kinetic energy?
The airplane
True
The type of energy in a moving object is:
Kinetic energy
Kinetic energy depends on:
mass and speed
T
Potential energy/ elastic potential energy
With no friction and pendulum will transfer energy between which two energy stores?
KE and GPE
a. Energy is the ability to do work.
b. Energy is neither created nor destroyed.
c. Potential energy is the energy of motion.
C
Non contact
Potential
The total amount of energy in a system is also called the _______ energy.
Mechanical
Potential
A change in motion is caused by an __________ force
unbalanced
Why is speed a more important factor in a vehicle collision than mass?
KE increases with the square of the speed. Speed increased KE more than mass.
(KE increases at the same rate as mass)
What is the law of conservation of energy?
Energy cannot be destroyed only transferred
poles
Friction
