Identify Newton's Law of Motion

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law of Motion, also known as the Law of Inertia, states that an object at rest will remain at rest, and an object in motion will continue 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

Newton's 2nd Law of Motion states that 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 with the formula F=ma.

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What does the term 'inertia' mean?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

Front

Provide an example of Newton's 1st Law of Motion.

Back

A glass sliding across a table will continue to slide until it hits an obstacle or friction slows it down.

Front

What is the formula for Newton's 2nd Law of Motion?

Back

The formula for Newton's 2nd Law of Motion is F = ma, where F is the force, m is the mass, and a is the acceleration.

Front

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

Back

According to Newton's 2nd Law, as mass increases, acceleration decreases if the same force is applied. This means heavier objects require more force to accelerate.

Front

What is an example of Newton's 3rd Law of Motion?

Back

When you jump off a small boat, you push the boat backward as you move forward. The action of you jumping forward results in the reaction of the boat moving backward.

Front

What is the significance of the net force in Newton's 2nd Law?

Back

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

Front

What happens to an object in motion if no net force acts on it?

Back

If no net force acts on an object in motion, it will continue to move at a constant velocity in a straight line.
