Which Law is It?

Front

What is the Law of Inertia (1st Law)?

Back

The Law of Inertia 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

What is the Law of Force & Acceleration (2nd Law)?

Back

The Law of Force & Acceleration 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 expressed as F=ma.

Front

What is the Law of Action/Reaction (3rd Law)?

Back

The Law of Action/Reaction states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Give an example of the Law of Inertia in everyday life.

Back

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

Front

Give an example of the Law of Force & Acceleration in everyday life.

Back

If you push a shopping cart, it accelerates in the direction of the push. The harder you push (more force), the faster it accelerates.

Give an example of the Law of Action/Reaction in everyday life.

Back

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

Front

What does it mean when we say an object has 'mass'?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

How does mass affect acceleration according to the 2nd Law?

Back

According to the 2nd Law, if the mass of an object increases, the acceleration decreases for a given force.

Front

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

Back

The relationship is defined by the equation F=ma, where F is force, m is mass, and a is acceleration.

Front

What is an example of a scenario illustrating the 3rd Law?

Back

When a swimmer pushes water backwards with their hands, they move forward in the opposite direction.
