Gravity and Friction

Question 1

an even distribution of weight enabling someone or something to remain upright and steady.

Answer 1

balance

Question 2

strength or energy as an attribute of physical action or movement

Answer 2

force

Question 3

the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton’s laws of gravity apply, with minor modifications to take the general theory of relativity into account.

Answer 3

gravity

Question 4

a coherent, typically large body of matter with no definite shape.

Answer 4

mass

Question 5

the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes.

Answer 5

newton

Question 6

type of weighing scale. It consists of spring fixed at one end with a hook to attach an object at the other.

Answer 6

spring scale

Question 7

the weight of an object is usually taken to be the force on the object due to gravity.

Answer 7

weight

Question 8

the resistance that one surface or object encounters when moving over another.

Answer 8

friction

Question 9

the continuous physical force exerted on or against an object by something in contact with it.

Answer 9

pressure

Question 10

the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great

Answer 10

volume
