Newton's 1st law Test

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What happens to a book on a car seat when the car suddenly stops?

Back

The book continues moving forward due to inertia.

Front

What unit is used to measure force?

Back

Newton (N).

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

How does surface roughness affect friction?

Back

Rough surfaces have greater friction compared to smoother surfaces.

Front

What is net force?

Back

The combined forces acting on a particular object.

Front

What happens to gravitational force as objects get closer?

Back

Gravitational forces increase.

Front

What is the relationship between mass and inertia?

Back

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

Front

What is the effect of a net force of zero on an object?

Back

The object will maintain its current state of motion (either at rest or moving at a constant velocity).
