Test Review Force and Motion

Front

What is the difference between speed and velocity?

Back

Velocity tells you both speed and direction.

Front

What does a graph showing a downward slope indicate?

Back

Deceleration (slowing down)

Front

What are examples of unbalanced forces?

Back

A car speeding up, a dog slowing down, and a person turning around the block.

Front

What does Tim's fall at 35mph describe?

Back

Tim's velocity.

Front

When does a car undergo acceleration?

Back

When it speeds up, slows down, or makes turns.

Front

Define speed.

Back

Speed is the distance traveled per unit of time.

Front

Define velocity.

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity.

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 cause an object to accelerate in the direction of the net force.
