1.When an object is at rest, which of the following is true?

• There are no forces acting on it.

• There are forces acting on it, but these forces are balanced.

• There is just one force acting on it, which is gravity.

The first law of motion states that if all the forces acting upon an object are BALANCED, then there will be:

• change in motion

• acceleration
• constant velocity
• no change in motion

No acceleration means:

• constant velocity OR the object is stationary

• Increasing velocity OR the object is stationary

• decreasing velocity OR the object is stationary

• None of these

An object at rest will _______ if no outside forces are applied.

• stay at rest
• decrease mass

• increase force

• in motion

A(n) __________ is a push or pull.

• newtons

• force

• momentum

An object at rest will stay at rest and an object in motion will stay in motion until an unbalanced force is acted upon it

• Newton's First Law of Motion
• Law of Gravitation
• Newton's Third Law of Motion

• Newton's Second Law of Motion

Which of the following explains the difference between speed and velocity?

• One has motion, the other does not

• One is fast and one is not.

• One involves time, and the other does not.

• One has direction, and the other does not
