CFA #3 - Physics

A push or a pull is called a(n)

• force

• acceleration

• inertia

• motion

Swimming of fish in water can be explained by which of the following Laws

• 1st

• 2nd

• 3rd

• None

Things will keep moving if no external force is applied

• 1st

• 2nd

• 3rd

• None

Which of the Newton's Laws state that forces act in pairs?

• 1st

• 2nd

• 3rd

• None

Which law helps us understand the impact of forces on objects of different masses?

• 1st

• 2nd

• 3rd

• None

The tendency of an object to resist any change in its motion is known as...

• acceleration

• inertia

• force

• balance

What is the formula for finding the speed of an object?

• distance/time

• time/distance

• distance*time

• distance+time

If the speed of an object does NOT change, the object is traveling at a(n)

• constant speed

• average speed

• increasing speed

• decreasing speed

in graphing motion, the steepness of the slope depends on

• how quickly or slowly the object is moving

• how far the object has moved

• when the object began moving

• the direction the object is moving

On a graph showing distance versus time, a horizontal line represents an object that is

• moving at a constant speed

• increasing its speed

• decreasing its speed

• not moving at all
