Newton's first law of motion

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia. This means it will be harder to change its motion.

Front

What is the unit of measurement for force?

Back

The unit of measurement for force is newtons (N).

Front

What happens to a moving object when balanced forces act on it?

Back

The object will continue to move at a constant speed and in the same direction.

Front

Why does a heavier object have more inertia than a lighter object?

Back

A heavier object has more mass, which means it has more inertia and is harder to accelerate or decelerate.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when a soccer player kicks a stationary ball, causing it to move.

Front

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

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is an example of inertia in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion, causing objects to slow down or stop.
