Lesson 2 Newtons Three Law Of Motion

Question 1

Refers to an object’s change in position upon application of force by another object.

Answer 1

Motion

Question 2

Who introduced the theory of impetus which is a concept similar to force according to the theory when impetus decreases to the speed of the object also decreases when that impetus is removed the object stops moving.
A.Galileo Galilei
B.Isaac Newton
C.Jhon Philopunos
D.Jean Buridan
E.Aristotle

Answer 2

C.

Question 3

Who said also in theory of impetus according to him motion is possible through a mover that keeps the object moving with power proportional to the speed and mass of the object. When the mover is removed the object stops moving he later named impetus as force.

Answer 3

Jean Buridan

Question 4

Who disagreed with aristotle’s claim he said even without a continuous application of force an object can continue moving with a constant speed through a straight line if there is no outside forces acting on it.

Answer 4

Galileo galilei

Question 5

He is famous for his Three Laws of motion,he is an english mathematician and physicist born on January 4,1643 in UK.

Answer 5

Isaac Newton

Question 6

He said that for object to move force must act a planet but when that force is removed the object comes to rest this lasted approximately 2,000 years ago

Answer 6

Aristotle

Question 7

Which law of motion requires the use of seat belt in cars.

Answer 7

First law (Law of Inertia)

Question 8

Newton’s first law of motion law of inertia states that

Answer 8

An object at rest remain at rest. An object in motion will continue to move at a constant velocity unless acted upon by a net force.

Question 9

A tendency of an object to maintain its state of rest or of uniform velocity in a straight line

Answer 9

Inertia

Question 10

In newton’s first law of motion law of inertia; does inertia depends on objects mass?

Answer 10

Yes

Question 11

In newton’s second law; law of acceleration what does it state

Answer 11

The law of acceleration states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to the objects mass

Question 12

What law of motion is the direction of the accele

Question 13

The love acceleration is expressed through this equation.

Answer 13

ΣF=ma

Question 14

Net Force Prb.
A 1,000 kg truck is traveling at an acceleration of 4.5 m/s²,east. Find the net force needed to accelerate the truck

Answer 14

4, 500N,east

Question 15

Acceleration Prb.
A boy rolls a 200g baseball horizontally on the floor with a net force of 2N to the right. What is the acceleration of the baseball?

Answer 15

10m/s²

Question 16

Mass Prb.
A box is pushed with an applied force of 20N parallel to the floor. It accelerated at 1.50 m/s² to the right. A parallel applied force of 10 N on the opposite side slow down the motion of the box. Neglecting friction what is the mass of the box?

Answer 16

6.67kg

Question 17

Measure the gravitational force of the weight of earth if its mass is equal to 40 kg.

Answer 17

392N

Question 18

Which law states that for every action there is an equal and opposite reaction.

Answer 18

Third law; Law of Interaction

Question 19

In this law not only you are exerting a force the object is also exerting a force back on you, the force exerted or any object is always exerted back by an equal magnitude of force but in opposite direction, and forces comes in pairs these are called reaction and action forces.

Answer 19

Law of Interaction

Question 20

The ___ that requires force while the ____ force that counteracts the ____ force

Answer 20

Action force–Reaction force–Action force
