Force and Motion 2023

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

How do you calculate force?

Back

Force is calculated using the formula: Force = Mass x Acceleration (F = m*a).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What happens to an object in motion if no net force acts on it?

Back

It will continue to move at a constant velocity.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What is the effect of gravity on falling objects?

Back

All objects fall at the same rate in a vacuum, regardless of their mass, due to gravity.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.
