What is energy defined as?
Energy is the ability to do work.
What is mechanical energy?
The sum of gravitational potential energy and kinetic energy.
What is the formula for mechanical energy?
Ek + Ep.
What is gravitational energy?
The energy an object has due to its position in the gravitational field relative to some reference point.
What is the formula for gravitational potential energy?
Ep = mgh or U = mgh.
What is the value of g in the formula for gravitational energy?
g = 9.8 m/s².
What is kinetic energy?
The energy an object possesses as a result of its motion.
What is the formula for kinetic energy?
Ek = \frac{1}{2}mv^2.
What is the principle of conservation of mechanical energy?
The total mechanical energy in an isolated system remains constant.
What is the formula for the principle of conservation of mechanical energy?
Ek1 + Ep1 = Ek2 + Ep2.
