4.16 Kinetic Energy Flashcards
1
Q
What is kinetic energy?
A
The energy that something possesses, due to its motion
2
Q
What does the kinetic energy of something depend on?
A
The object’s mass and speed
3
Q
Energy is always conserved. So if you assume there are no frictional forces, how can you link kinetic energy and gravitational potential energy?
A
As energy is gained by the kinetic store, energy is lost by the gravitational potential store and vice versa
4
Q
If something light and something heavy was travelling at the same speed, which one would have more kinetic energy?
A
The heavy object
5
Q
Which two measurements are required to calculate the kinetic energy of an object?
A
- Velocity
- Mass
6
Q
What are the units for kinetic energy?
A
Joules (J)
7
Q
The units for mass when calculating kinetic energy should be:
A
Kilograms (kg)
