When more than one force acts on an object, the two forces: (combine / cancel / balance)

combine

The change in speed or direction of an object causes _______________

accelleration

a force is defined as a __________ or a ___________

push / pull

The amount of matter in an object

mass

If the effects of forces cancel each other out and do not cause an object to move, the forces are _________________

balanced

The size and magnitude of a force in a specific direction

vector

If forces do NOT cancel each other out and one is stronger, then the forces are ______________________

unbalanced

Two forces that produce a net force of zero will cause the forces to (combine / cancel / accelerate)

cancel

An unbalanced force will cause a _______________________

change in motion

When two arrows of force point in opposite directions you (add / subtract / multiply)

subtract

When two arrows of force point in the SAME direction, you (add / subtract / multiply)

add

The strength or magnitude of force is measured in what unit?

Newtons

If 15 Newtons are going left, and 10 Newtons are going to the right, the net force is _____________________ in the _______________________ direction.

5, left

If 15 Newtons are going right, and another 10 Newtons are going right, the net force is _______________________ in the _________________________ direction.

25, right

If two teams are playing tug of war, will you add/combine the two forces or would you subtract/separate the two forces?

subtract / separate

If two men are pushing a car down the street, would you add/combine the two forces or would you subtract/separate the two forces?

add / combine

When using UNIT RATES (like minutes per second) what mathematical operation would you use to calculate the amount of FORCE?

multiply

When using UNIT RATES (like minutes per second) what mathematical operation would you use to calculate the amount of MASS the object has?

divide

What is the formula for finding the NET FORCE of an object?

Net Force = mass * acceleration

A baseball traveling through the air at 95 miles per hour is an example of (speed / acceleration / velocity)

speed

A train starts from a complete stop and then increases to a speed of 140 miles per hour squared.

accelleration

A balloon travels south at .5 miles per hour squared.
