What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the law of action-reaction?

Back

The law of action-reaction states that for every action, there is an equal and opposite reaction.

Front

What happens to energy when natural gas is burned?

Back

When natural gas is burned, its chemical energy transforms into thermal energy, which can then be used to heat water or produce sound energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the greater the mass of an object, the more force is required to accelerate it.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.
