PS.6 Identify Newton's Laws of Motion warm up

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 unless acted upon by a net external 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 (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

Example of Newton's 1st Law: A boy pulling his wagon down the street. What happens when he stops?

Back

The wagon continues moving due to inertia.

Front

Example of Newton's 2nd Law: Pushing a loaded truck vs pushing an unloaded truck. Which requires more force?

Back

Pushing a loaded truck requires more force due to its greater mass.

Front

Example of Newton's 3rd Law: An ice skater pushes back with their skate. What happens?

Back

The skater accelerates forward due to the reaction force.

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 mass affect acceleration according to Newton's 2nd Law?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is an example of Newton's 3rd Law in everyday life?

Back

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

Front

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

Back

F = ma (Force = mass x acceleration).
