Back 2

Friction

Front 3

Friction can also occur between objects at _______.

Back 3

Rest

Front 4

When the net force of an object is zero, the acceleration is ___________.

Back 4

Zero

Front 5

An object with a mass of 1-kg on Earth weighs how much (N)?

Back 5

10N

Front 6

A object is pulled northward by a force of 10N and is also being pulled southward by a force of 25N. What is the resultant force?

Back 6

15N

Front 7

What is the ratio of kg to N on Earth?

Back 7

1-kg to 10N

Front 8

Your weight measured on a scale is technically measuring:

Back 8

Force due to gravity acting on you

Front 9

If the mass of a cart is quickly loaded to have twice the mass while propulsion remains constant, acceleration is:

Back 9

Halved

Front 10

An object moving at a constant velocity, an object at rest, and an object in mechanical equilibrium all have___________.

Back 10

Zero Acceleration

Front 11

When an object is suspended by a vertical rope, and the block accelerates upward by the rope, the rope's tension is:

Back 11

Greater than its weight

Front 12

Neglecting friction, a large and small block begin to slide down an incline at the same time. The smaller block reaches the bottom in what relation to the larger block?

Back 12

At the same time

Front 13

A rocket with a sustained and constant upward force has an increasing acceleration because:

Back 13

Mass decreases as fuel is used

Front 14

If less horizontal force is applied to a sliding object than is needed to maintain constant velocity, the object eventually:

Back 14

Stops

Front 15

The quantity of matter in an object.
Measure of the inertia or sluggishness that an object exhibits in response to any effort to start, stop, or change it's motion.

(kg)

Back 15

Mass

Front 16

Force upon an object due to gravity
(N or lb)

Back 16

Weight

How is Acceleration proportional to mass?

Back 17

Inversely
Acceleration ~ (1/mass)

Front 18

Acceleration =

Back 18

(net force)/(mass)

Nonfree Fall

Front 20

Non-Free Fall depends on _____

Back 20
