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 stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

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

Back

A frog leaping 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.

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

Back

When Rocky and Parker skip pebbles, the pebbles thrown by Parker go farther and faster than those thrown by Rocky due to the greater force applied.

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 a child pushes off the ground while pulling a sled, the ground pushes back with an equal force, allowing the child to move.

Front

What does the equation F = ma represent?

Back

It represents Newton's 2nd Law of Motion, where F is the force applied, m is the mass of the object, and a is the acceleration produced.

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 inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

What is an example of inertia in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia.
