Kinetic Energy Flashcards
1
Q
What happens to the kinetic energy when work is done?
A
Kinetic energy is transferred when work is done
2
Q
What happens to the kinetic energy of a car when work is done by the breaks?
A
The kinetic energy is transferred into heat energy as friction between the wheels and break pads
3
Q
What happens to potential energy when kinetic energy is gained?
A
When kinetic energy is gained, potential energy is lost
4
Q
Why do smaller meteors not make it through the atmosphere?
A
Because the heat caused by the friction between the meteor and the particles causes the meteor to burn up
5
Q
What is the equation for kinetic energy?
A
Kinetic energy = 1/2 x mass x speed(^2)
