Kinetic energy Flashcards
1
Q
Kinetic energy transferred is [ ]
A
work done
2
Q
In order to stop an object with kinetic energy, that energy must be …
A
transferred into other types
3
Q
What does conservation of energy state?
A
Energy can never be created or destroyed - only converted into different forms
4
Q
To stop a car, kinetic energy has to be converted to [ ] energy as [ ] between the wheels and the brake pads, causing the [ ] of the breaks to increase
A
heat
friction
temperature
5
Q
What is the equation for kinetic energy transferred?
A
Kinetic energy transferred = Work done 1/2 * m * v² = F * d m = mass (kg) v = speed (m/s) F = force (N) d = distance (m)
6
Q

Kinetic energy gained = [ ] lost
A
Potential energy
