Newton's Laws Vocabulary Quiz

the rate at which an object moves; depends on the distance traveled
and the time taken to travel that distance

• speed

• velocity

• acceleration

• net force

The difference between speed and velocity is that velocity will have ​ (a)  

• direction.
• acceleration
• a net force

An object is accelerating if the object speeds up, slows down, or changes direction.

• True

• False

Acceleration that occurs in a circular motion is called ​ (a)   . Acceleration in which an object slows down is called ​ (b)   .

• centripetal acceleration
• deceleration
• acceleration
• net force

A ___________ is a push or a pull on an object.

• air resistance

• gravity

• force

• form of work

A ________________ is used to make work easier. Some of the types include wedge, inclined plane, lever, pulley, screw, wheel and axle.

• compound machine

• simple machine

• mechanical advantage

• mechanical efficiency

​ (a)   is the force that opposes motion when an object is in contact with a surface. This force will push back on an object.

• Friction
• Air resistance
• Gravity
• Fluid

Reorder the following Newton's Laws from 1st to 3rd.

• Acceleration depends on mass and force.

• An object in motion will stay in motion and an object at rest will stay at rest unless a force is applied.

• For every action there is an equal but opposite reaction.

A force of attraction between objects that is due to their masses.

• Velocity

• Terminal Velocity

• Gravity

• Resultant Velocity

When the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity then ​ (a)   will be reached.

• terminal velocity
• negative acceleration
• positive acceleration
• deceleration
