2 Which of these is one of Newton's laws of motion?
A An object's momentum is the product of its
mass and velocity.
B A moving object will continue moving until a
force acts upon it.
C The force of gravity is proportional to the
inverse square of the distance.
D The rate at which an object falls depends on the
height from which it is dropped.

 A moving object will continue moving until a

force acts upon it.

Explanation:

if you roll a ball it will continue to roll until a outside force acts upon it

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
