Newton Law Practice

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 with the same speed and in the same direction unless acted upon by a net external force.

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 is often expressed as F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

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

Front

How does mass affect acceleration?

Back

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

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

What happens to a passenger in a car when it suddenly stops?

Back

The passenger continues to move forward due to inertia, which is an example of Newton's 1st Law.

Front

If a force of 10N is applied to a 2kg object, what is its acceleration?

Back

Acceleration (a) can be calculated using F = ma. Here, a = F/m = 10N/2kg = 5m/s².

Front

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

Back

Force is the product of mass and acceleration, meaning that greater force results in greater acceleration for a given mass.

Front

What is an example of Newton's 3rd Law in everyday life?

Back

When you jump off a small boat, you push the boat backward as you move forward.
