Newton's Laws

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. All objects with mass have inertia.

Front

What is the net force on an object at rest?

Back

The net force on an object at rest is 0 N, as the forces acting on it are balanced.

Front

What does Newton's 2nd Law state?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What happens to an object in frictionless space after a force is applied?

Back

Once a force is applied and the object is in frictionless space, no additional force is needed to keep it moving; it will continue in motion indefinitely.

Front

Can an object with zero net force be moving?

Back

Yes, an object with zero net force can be moving at a constant velocity.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

In Newton's 2nd Law, as mass increases, acceleration decreases for a given force.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is an example of an object with high inertia?

Back

A bowling ball has high inertia due to its large mass, making it harder to start or stop moving.

Front

What does Newton's 3rd Law state?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.
