Mass

Question 20

The standard unit of time is the second (s)

Answer 20

Time

Question 21

Sometimes called speed, is a “measure of how fast something is moving”, or more precisely, the rate of change of it’s position

Answer 21

Velocity
v=d/t

Question 22

“the rate of change of velocity” with time is acceleration. It is how “quickly or slowly” the velocity is changing. Because the velocity is divided by time, the unit meters per second squared(m/s^2)

Power P=W/t

Question 27

The product of the mass of an object and it's velocity. Represented by small letter p

Answer 27

Momentum P=mv

Question 28

Is the property of matter that acts to resist a "change in its state of motion"

Answer 28

Newton's first law:Inertia

Question 29
