Newtons laws of motion review part 1

Front

What is Newton's First 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

Define the Law of Inertia.

Back

The Law of Inertia states that an object will not change its state of motion unless a force is applied to it.

Front

Give an example of the Law of Inertia.

Back

A billiard ball rolling on a table continues to roll until it hits another ball or the edge of the table.

Front

What is Newton's Second 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

Define the Law of Acceleration (F=MA).

Back

The Law of Acceleration states that the force acting on an object is equal to the mass of that object multiplied by its acceleration.

Front

Give an example of the Law of Acceleration.

Back

A person carrying a heavy backpack will walk slower than a person carrying a lighter backpack.

Front

What is Newton's Third Law of Motion?

Back

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

Front

Define the Law of Action-Reaction.

Back

The Law of Action-Reaction states that for every force exerted, there is a force of equal magnitude but in the opposite direction exerted back.

Front

Give an example of the Law of Action-Reaction.

Back

When a hammer strikes a nail, the nail exerts an equal force back on the hammer.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.
