 Questions 5 Focus Forces and Energy Topics Force, Kinetic Energy, Power, Weight Question Type Questions

#### Study Guide

###### Force

Force is applied to change an object's speed or direction of motion.

###### Kinetic Energy

Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.

###### Power

Power is the rate at which work is performed or work per unit time: $$P = {w \over t}$$ and is measured in watts (W).

###### Weight

Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
