Newton's Laws Examples

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 an unbalanced 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

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

Back

As mass increases, for a given force, the acceleration decreases.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A passenger in a car lurches forward when the car suddenly stops.

Front

What is inertia 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 can you demonstrate Newton's 2nd Law with a simple experiment?

Back

By using a cart and weights, you can show that increasing the weight (mass) decreases the acceleration for a constant force.

Front

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

Back

Force equals mass times acceleration (F=ma), meaning that a greater force results in greater acceleration.

Front

Can you give an example of Newton's 3rd Law in action?

Back

When a swimmer pushes water backward with their arms, they move forward due to the reaction force of the water pushing them.

Front

What happens to a sled when a child stops pulling it, according to Newton's 1st Law?

Back

The sled continues to move forward due to its inertia until acted upon by another force (like friction or hitting an object).
