Front

What is air resistance?

Back

A type of friction that occurs when air pushes against a moving object, causing it to decelerate.

Front

What type of energy is associated with heat?

Back

Thermal energy is the energy that comes from the temperature of matter.

Front

How do you calculate power?

Back

Power is calculated by dividing work done by the time taken (Power = Work/Time).

Front

What happens to objects in a vacuum when dropped?

Back

In a vacuum, all objects fall at the same rate regardless of their mass.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv².

Front

What is the formula for work?

Back

Work is calculated as Work = Force x Distance.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass x Gravity.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.
