Identifying Newtons Laws

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

How does mass affect inertia?

Back

More mass means more inertia. Heavier objects are harder to start or stop moving compared to lighter objects.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law 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 as the formula: Force = mass x acceleration (F = m x a).

Front

What is Newton's Third Law of Motion?

Back

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

Give an example of Newton's First Law in everyday life.

Back

A book resting on a table will remain at rest until someone pushes it.

Give an example of Newton's Second Law in everyday life.

Back

If you push a shopping cart, it will accelerate faster if it is empty (less mass) than if it is full (more mass).

Give an example of Newton's Third Law in everyday life.

Back

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

Front

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

Back

The relationship is defined by Newton's Second Law: Force = mass x acceleration (F = m x a). This means that increasing the force will increase the acceleration if the mass remains constant.

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.
