1
Q
What is the formula for gravitational potential energy?
A
Ep = mgh
Energy (gravitational potential energy/measured in joules) = mass (kg) x gravitational field strength (N/kg) x height (cm)
2
Q
How do you transfer heat without particles?
A
Radiation
3
Q
What is the equation for kinetic energy?
A
Ek = 1/2 MV^2
Energy (kinetic) = 1/2 Mass (kg) x Velocity^2
4
Q
What is an open system?
A
A system that energy and matter can escape from.
5
Q
What is gravity?
A
A force of attraction between two objects, depending on the mass and the distance between the two objects.
6
Q
How well objects transfer energy by conduction is known as what?
A
Thermal Conductivity
7
Q
What is the gravitational field strength of Earth?
A
(9.8 N/kg)
