Forces and Motion Review

Front

What is friction?

Back

Friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with another stable object.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will move in the direction of the larger force.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls us toward the Earth.

Front

What does it mean for forces to be balanced?

Back

Balanced forces mean that the total net force acting on an object is zero, resulting in no change in motion.

Front

If an object is at rest, what can we say about the forces acting on it?

Back

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

Front

What is an example of friction?

Back

An example of friction is when you slide a book across a table and it slows down due to the friction between the book and the table.

Front

What direction does an object move if the net force is to the right?

Back

If the net force is to the right, the object will move to the right.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is when one person pushes a swing harder than another person, causing the swing to move.
