Newton's Laws

Question 1

an object moves at a constant velocity unless an unbalanced force acts on it

Answer 1

Newton’s First Law of Motion

Question 2

if an object is at rest, its velocity is zero and it stays at rest unless an unbalanced force acts on it

Answer 2

Newton’s First Law of Motion

Question 3

Law of Inertia

Answer 3

Newton’s First Law of Motion

Question 4

a greater force would be needed to change the motion of the bowling ball because

Answer 4

it has a greater inertia

Question 5

the smaller an objects mass is,

Answer 5

the smaller its inertia is

Question 6

the motion of an object changes only if an unbalanced force acts on the object

Answer 6

Newton’s Second Law

Question 7

describes how the forces exerted on an object, its mass, and its acceleration are relation

Answer 7

Newton’s Second Law

Question 8

the change in velocity divided by the time it takes for the change to occur

Answer 8

Acceleration

Question 9

can be used to calculate the net force if mass and acceleration are known

Answer 9

Newton’s second law

Question 10

states an object’s acceleration is in the same direction as the net force on the object and is equal to the net force exerted on it divided by its mass

Answer 10

Newton’s second law

Question 11

(net force)/mass

Answer 11

acceleration

Question 12

a = F(net)/m

Answer 12

Acceleration

Question 13

the sum of all of the forces on an object

Answer 13

net force

Question 14

one object exerts a force on a second object, the second object exerts a force on the first that is equal in strength and opposite in direction

Answer 14

Newton’s Third Law

Question 15

to every action there is an equal and opposite reaction

Answer 15

Newton’s Third Law

Question 16

One force doesn’t cause another force

Answer 16

Newton’s Third Law

Question 17

The forces occur at the same time

Answer 17

Newton’s Third Law

Question 18

Forces on different objects

Answer 18

do not cancel

Question 19

action and reaction forces act on

Answer 19

different objects

Question 20

Net Force = 0

Answer 20

the object doesn’t move

Question 21

interactions between objects

Answer 21

forces

Question 22

if two objects have different masses the will feel the _____ size force

Answer 22

same

Question 23

the tendency of an object to resist a change in motion

Answer 23

inertia

Question 24

the acceleration of an object depends on its mass and the net force exerted on it.

Answer 24

Newton’s Second Law

Question 25

the motion of an object at rest or moving with a constant velocity will not change unless acted an unbalanced force acts on the object

Answer 25

Newton’s First Law

Question 26

when an object exerts a force on a second object, the second object exerts a force on the first object

Answer 26

Newton’s Third Law
