Front

What is inertia?

Back

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

Front

What is momentum?

Back

Momentum is the quantity of motion an object has, which depends on its mass and velocity.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is friction?

Back

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

Front

What is an outside force?

Back

An outside force is any force that comes from outside an object and can change its motion.

Front

What happens to an object in motion if no forces act on it?

Back

It will continue to move in a straight line at a constant speed due to inertia.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes all objects to fall towards the Earth at the same rate, regardless of their mass.
