Which Newton Law Is It?

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 unless acted upon by a net external force. This is also known as the Law of Inertia.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed with the formula F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

Define 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

Give an example of Newton's 1st Law in everyday life.

Back

A book resting on a table will remain at rest until someone pushes it.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, for a given force, the acceleration decreases. This means heavier objects require more force to accelerate.

Front

Provide an example of Newton's 3rd Law in action.

Back

When a swimmer pushes water backwards with their hands, they move forward in the opposite direction.

Front

What is the formula for calculating force in Newton's 2nd Law?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

Explain the concept of net force.

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

What happens to an object if the net force acting on it is zero?

Back

If the net force is zero, the object will maintain its current state of motion, either at rest or moving at a constant velocity.
