Question | Answer |
what is energy | the ability to do work or cause change |
how is energy measured | in joules |
what is power | the rate at which work is done |
what is potential energy | energy that results from the position or shape of an object |
what is kinetic energy | the energy an object has due to its motion |
what is gravitational potential energy | energy related to an objects height |
what is elastic potential energy | the energy associated with objects that can be stretched or compressed |
how do you calculate an objects mechanical energy | by adding the potential energy and the kinetic energy together |
what s thermal energy | the total potential and kinetic energy of the particles in an object |
what is the law of conservation of energy | it states that when one form of energy is transformed to another, no energy is lost in the process.also, it states that energy cannot be created or destroyed |
what is motion | the state in which one objects distance from another is changing |
what is a reference point | a place or an object used for comparison to determine if something is in motion or not |
what is velocity | speed in a given direction |
how does an object accelerate | by increasing speed, decreasing speed, or changing direction |
what is deceleration | slowing down or a decrease in velocity |
