What is Physics?

Back

Physics is the branch of science that studies matter, energy, and the interactions between them.

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter.

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

What is work in scientific terms?

Back

In science, 'work' is the transfer of energy when a force moves an object.

Front

What is energy?

Back

Energy is the capacity to do work or produce change.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.
