Newton's Laws Examples

Front

What is Newton's 1st Law of Motion?

Back

Also known as the Law of Inertia, it states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

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

Back

A frog leaping upward off a lily pad is pulled down by gravity and lands on another lily pad instead of continuing in a straight line.

Front

What is Newton's 2nd Law of Motion?

Back

It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, expressed as F=ma.

Give an example of Newton's 2nd Law of Motion.

Back

If you push a sled, it accelerates in the direction of the force applied, and the more force you apply, the faster it goes.

Front

What is Newton's 3rd Law of Motion?

Back

It states that for every action, there is an equal and opposite reaction.

Give an example of Newton's 3rd Law of Motion.

Back

When you paddle a canoe, the canoe goes forward as a reaction to the force you apply to the water.

Front

What does inertia mean in the context of Newton's 1st Law?

Back

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

Front

How does Newton's 1st Law explain why a child pulling a sled can get hit by it after stopping?

Back

The sled continues to move due to inertia until acted upon by another force, such as friction or a collision.

Front

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

Back

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

Front

How does the mass of an object affect its acceleration according to Newton's 2nd Law?

Back

A larger mass will result in less acceleration for the same amount of force applied.
