5.2&5.3 Motion, Energy and Force Review

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, and electrical.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What are the two main factors that describe motion?

Back

Motion is described by an object's direction and speed.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light. It is the energy that travels through space.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices and appliances.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of an object. It is the total kinetic energy of the particles in a substance.

Front

What is force?

Back

Force is a push or pull on an object that can cause it to change its motion. It is measured in newtons (N).
