Force and Motion Review

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, helping to slow it down or stop it.

Front

Why is friction important?

Back

Friction is important because it allows us to walk without slipping, helps vehicles stop, and enables objects to stay in place.

Front

What does it mean if an object is at rest?

Back

If an object is at rest, it means that the forces acting on it are balanced.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

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 an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account both magnitude and direction.

Front

How does distance affect gravitational force?

Back

As objects move closer together, the gravitational force between them increases.
