Front

What is the formula to calculate force?

Back

Force (F) = Mass (m) × Acceleration (a)

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as PE = mgh (mass × gravity × height).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv² (1/2 × mass × velocity squared).

Front

What is the relationship between mass, force, and acceleration?

Back

According to Newton's second law, 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.

Front

How does height affect gravitational potential energy?

Back

As the height of an object increases, its gravitational potential energy increases.

Front

What happens to kinetic energy as an object speeds up?

Back

As an object's speed increases, its kinetic energy increases exponentially, since KE = 1/2 mv².

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If an object has a mass of 4 kg and accelerates at 5 m/s², what is the force applied?

Back

Force = 4 kg × 5 m/s² = 20 N.

Front

What is the potential energy of a 2 kg object at a height of 10 m?

Back

PE = mgh = 2 kg × 9.8 m/s² × 10 m = 196 Joules.
