Force & Motion Flashcard (6.7ABC)

Front

What is mass?

Back

Mass is the amount of matter in an object.

Front

What is weight?

Back

Weight is the force of gravity acting on an object.

Front

How are mass and weight related?

Back

Mass is the amount of matter in an object, while weight is the force of gravity on that object.

Front

What is a contact force?

Back

A contact force is a force that acts on an object through direct contact.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts on an object without direct contact, such as gravity.

Front

Give an example of a contact force.

Back

Friction is an example of a contact force.

Front

Give an example of a non-contact force.

Back

Gravity is an example of a non-contact force.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

If a person pushes a box with 20 N to the right and friction exerts 15 N to the left, what is the net force?

Back

The net force is 5 N to the right.

Front

What type of force is gravity?

Back

Gravity is a non-contact force.
