Physical Science Exam Review PART 2

Front

What enables a motorcycle to roll?

Back

Rolling friction is the force that allows a motorcycle to roll smoothly over a surface.

Front

Which state of motion is NOT accelerating?

Back

Moving at a constant velocity means there is no change in speed or direction, hence it is not accelerating.

Front

If the same force is applied to different objects, which will accelerate the most?

Back

A marble will accelerate the most because it has less mass compared to a science textbook, smartphone, or fishtank.

Front

What are examples of levers?

Back

A see-saw, a hammer, and a tennis racket are all examples of levers, which are simple machines that help lift or move loads.

Front

How do acidic solutions taste?

Back

Acidic solutions typically taste sour.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is the difference between sliding friction and rolling friction?

Back

Sliding friction occurs when two surfaces slide against each other, while rolling friction occurs when an object rolls over a surface.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to changes in speed or direction.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help lift objects with less effort.

Front

What is a wedge?

Back

A wedge is a simple machine that is used to split or cut objects apart, like a knife or an axe.
