Front

What is a force?

Back

A force is a push or a pull on an object.

Front

What happens to a passenger in a car when the driver slams on the brakes?

Back

The passenger will continue moving forward due to inertia.

Front

What is Newton's 1st Law of Motion also known as?

Back

The Law of Inertia.

Front

What does Newton's 1st Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the definition of inertia?

Back

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

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is a net force?

Back

The net force is the vector sum of all the forces acting on an object.

Front

How does a net force affect an object's motion?

Back

A net force causes an object to accelerate in the direction of the net force.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).
