#1
Front (Question)

Energy

Back (Answer)

The capacity of a system to do work

#2
Front (Question)

KE

Back (Answer)

KE= an object moving KE= 1/2mv^2 kgm^2/s^2

#3
Front (Question)

PE

Back (Answer)

PE= mgh kgm^2/s^2

#4
Front (Question)

Elastic potential energy

Back (Answer)

U=1/2kx^2 k=spring constant (n/m)

#5
Front (Question)

What happens to the kinetic energy of an object when its velocity is tripled?

Back (Answer)

The KE increases by a factor of 9. This is because 3^2=9

#6
Front (Question)

What are examples of potential energy?

Back (Answer)

Chemical, Elastic, electric, gravitational

#7
Front (Question)

Conservation of energy

Back (Answer)

Sum of all initial energy = sum of all final energies

#8
Front (Question)

Non-conservative force

Back (Answer)

Any force that causes energy to be lost from a system to the environment EX) friction and air resistance

#9
Front (Question)

Kinematics equation for conservation of energy

Back (Answer)

Vf^2= Vi^2 + 2a(change of)d

#10
Front (Question)

Work energy theorem

Back (Answer)

W=(change of)E

#11
Front (Question)

What increases an objects energy?

Back (Answer)

Work done on an object by its environment

#12
Front (Question)

What decreases an objects energy?

Back (Answer)

Work done by an environment by an object on its environment
