Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the difference between speed and velocity?

Back

Velocity includes direction, while speed does not.

Front

How does mass affect acceleration when a constant force is applied?

Back

Greater mass leads to less acceleration.

Front

What is thrust in the context of rocket launches?

Back

Thrust is the force that propels the rocket upward.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration.

Front

What happens to the force needed to accelerate an object if its mass increases?

Back

More force is needed to achieve the same acceleration.

Front

What is the definition of energy?

Back

Energy is the ability to do work or cause change.

Front

What is the principle of conservation of energy?

Back

Energy can neither be created nor destroyed, only transformed.

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical interaction, while non-contact forces act at a distance.

Front

What is an example of a contact force?

Back

Friction is an example of a contact force.
