FORCES AND NEWTON’S LAWS OF MOTION

Question 1

usually referred to as the pull or push exerted upon an object as it interacts with another object.

Answer 1

Force

Question 2

TWO TYPES OF FORCES

Answer 2

Contact Forces
Noncontact Forces

Question 3

causes an interaction that brings about
a direct physical contact between two objects.

Answer 3

Contact Forces

Question 4

Three Major Kinds of Contact Forces

Answer 4

Normal Force
Friction Force
Tension Force

Question 5

refers to the force exerted upon an
object by the surface with which it is in contact with.This force is perpendicular to the surface, regardless of its angle.

Answer 5

Normal Force

Question 6

refers to the force exerted upon an object by a surface, such that the force is parallel to it, i.e., heading against the direction the object is sliding.

Answer 6

Friction Force

Question 7

refers to the pulling force exerted
upon an object by a cord it is attached to.

Answer 7

Tension Force

Question 8

referred to as long-range or actionat-a-distance forces. These forces act between objects that are distant and are separated by vacant space.

Answer 8

Noncontact Forces

Question 9

Examples of Noncontact Forces

Answer 9

Magnetic force
Electric force
Gravitational force

Question 10

responsible for the repulsion or attraction between moving charged particles.

Answer 10

Magnetic force

Question 11

the force exerted by one electric charge to another, both for stationary and moving charges.

Answer 11

Electric force

Question 12

refers to the force responsible for attracting two objects that have mass, or the amount of matter
available in an object.

Answer 12

Gravitational force

Question 13

commonly distinguished from weight, which is the gravitational force exerted upon an object.

Answer 13

Mass

Question 14

NEWTON’S LAWS OF MOTION

Answer 14

First Law of Motion (Law of Inertia)
Second Law of Motion (Law of Acceleration)
Third Law of Motion (Law of Action and Reaction)

Question 15

The tendency of objects to remain in motion is referred to as

Answer 15

inertia

Question 16

When a force is exerted upon an object, it is accompanied by a given result in motion.

Answer 16

Superposition of Forces

Question 17

defined simply as a change in velocity. From the
First Law, when the net external force (or the combination of individual forces exerted on an object) is not zero, acceleration occurs

Answer 17

Acceleration

Question 18

an object’s resistance to motion relative to a surface against which it is sliding.

Answer 18

FRICTION

Question 19

The component vector parallel to the surface and perpendicular to the normal force is the

Answer 19

FRICTION FORCE

Question 20

The type of friction exerted on an object when it is sliding on a surface, such that the two surfaces are moving with respect to each other. The smoother or more slippery a surface is, the smaller its coefficient of kinetic friction.

Answer 20

Kinetic Friction Force

Question 21

contrasted against kinetic friction is the second type of friction that occurs when there is no relative motion between two surfaces.

Answer 21

Static Friction

Question 22

“if an object A applies a force on object B (FA on B), object B applies a force on object A (FB on A), such that the two forces comprise a respective
action and reaction pair.

Answer 22

Newton’s Third Law of Motion

Question 23

states that “every object continues in its state of rest, or of uniform velocity in a straight line, as long as no net force acts on it.”

Answer 23

The first law of motion
