Newtons First Law

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

What is an unbalanced force?

Back

A force that causes an object to change its state of motion (either starting, stopping, or changing direction).

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

How does mass affect inertia?

Back

More mass means more inertia, which means it is harder to change the motion of the object.

Front

What happens when two equal forces act in opposite directions?

Back

They create a balanced force, resulting in no change in motion.

Front

What is the relationship between force and motion?

Back

An unbalanced force is required to change the motion of an object.

Front

What is an example of friction in everyday life?

Back

When you slide a book across a table, friction slows it down.

Front

If a force of 10 N is acting upwards, what force is needed to balance it?

Back

A force of 10 N acting downwards.

Front

What does it mean for forces to be balanced?

Back

The net force is zero, and there is no change in the object's motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
