Potential and Kinetic Energy Flashcards
1
Q
What is the equation for gravitational potential energy?
A
gravitational potential energy = Mass(kg)gheight(m)
g = gravitational field strength (10 N/kg for earth)
2
Q
What is gravitational potential energy?
A
The energy that an object has by virtue of its vertical position in a gravitational field
3
Q
When an object is raised vertically, [ ] against the [ ] and the object gains gravitational potential energy.
A
work is done
force of gravity
4
Q
What is force of gravity measured in?
A
Joules (J)
5
Q
What is the formula for kinetic energy?
A
kinetic energy (J) = 1/2 * mass (kg) * speed² (m/s)
6
Q
What does kinetic energy depend on?
A
Mass and speed
