3
Q
What is the formula for Gravitational potential energy?
A
GPE= Mass (kg) x gravitational field strength (N/kg) x hight (meters)
4
Q
What is the formula for kinetic energy?
A
KE =1/2 x M (Mass) V (electricity) - speed squared. Squared
5
Q
What is the formula for power?
A
Power = Force/time
Power = current x voltage
6
