Laws of Motion

Front

A bird flapping its wings to fly is an example of...

Back

Newton's 3rd law of motion: For every action, there is an equal and opposite reaction.

Front

F=ma represents which of Newton's Laws?

Back

Newton's 2nd Law of Motion: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

The Law of Inertia states that...

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force (Newton's 1st Law).

Front

A cannonball firing is an example of what law?

Back

Newton's 3rd law of motion: The action of the cannonball being fired results in an equal and opposite reaction on the cannon.

Front

What does Newton's 1st Law of Motion describe?

Back

It describes the concept of inertia, stating that an object will not change its state of motion unless acted upon by a net external force.

Front

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

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

What is an example of Newton's 1st Law of Motion?

Back

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

Front

What does Newton's 3rd Law of Motion imply about forces?

Back

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

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
