'For every action, there is an equal but opposite reaction'

What is defined as the rate of motion in a given direction?

Solids moving against each other generate fluid friction

'The acceleration of a body is directly proportional to the force acting on it...'

When a force acts through a distance, [blank] is said to have been done

What can be defined as power or energy exerted against a body in a given direction?

What is defined as the quantity of material contained in a body?

What set of rules/laws are applied to motion in space?

Friction always acts in a direction.....

The weight can change, depending on location, while mass does not

In the English system the pound is used to indicate mass, though it's really a force unit 

In the English system the unit of power is [blank] and in the metric system it is [blank]

The rate at which work is done or energy is gained or expended is power

What is caused by the contact between the moving object and other substances around it?

What law is sometimes called the law of inertia?

Force's units in the English system are.....

What law is mathematically expressed by the formula F=ma?

One Newton-meter is equal to [blank]

What is the speed of light?

In the English system, the units of work are [blank], and in the metric system [blank].

Fluid friction is often called drag

Who said an object in horizontal motion would continue to move @ same speed with no add. force?

Force's units in the metric system are....

What is defined as the change in velocity per unit of time?

What is the science that deals with the motion of bodies moving through air and other gases?

What of a body is an expression of the amount of the force of gravity on it at a given time?

'A body at rest tends to remain at rest, and a body in motion tends to remain in motion...'
