Unit 2 Vocabulary Exam POE

Name:

A (a)   on an object.

• force
• magnitude
• vector
• displacement

The greatness of size or amount.

• force
• magnitude
• vector
• displacement

The location of something relative to something else.

• force
• magnitude
• vector
• direction

Not moving. An object is said to be at rest if it does not change its position with respect to its surroundings with time.

• force
• vector
• displacement
• at rest

A contact force that surfaces exert to prevent solid objects from passing through each other. If two surfaces are not in contact, they can't exert a normal force on each other.

• normal force
• applied force
• friction force
• displaced

A force that something or someone exerts on an object.

• normal force
• applied force
• friction force
• displacement

A measurement between the starting position and final position of an object regardless of the path followed. Displacement is described by a magnitude and direction, making it a vector quantity.

• normal force
• applied force
• friction force
• displaced

The force that resists motion when the surface of one object comes in contact with the surface of another is _____.

An object in a state of rest or uniform motion will continue to be so unless acted upon by a net force. This law describes the relationship between velocity and forces.

• Newton's 1st Law
• Netwon's 2nd Law
• Newton's 3rd Law
• none of these
