applications of newtons law

Question 1

What is Newton’s First Law of Motion?

Answer 1

An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by a net external force.

Question 2

True or False: Newton’s Second Law states that force equals mass times acceleration.

Answer 2

True

Question 3

Fill in the blank: The equation for Newton’s Second Law is ___ = mass × acceleration.

Answer 3

force

Question 4

What does Newton’s Third Law state?

Answer 4

For every action, there is an equal and opposite reaction.

Question 5

Multiple Choice: Which of the following is an application of Newton’s First Law? A) A car accelerating B) A ball rolling on a flat surface C) A rocket launching

Answer 5

B) A ball rolling on a flat surface

Question 6

What is the unit of force in the International System of Units (SI)?

Answer 6

Newton

Question 7

True or False: The acceleration of an object is directly proportional to the net force acting on it.

Answer 7

True

Question 8

Fill in the blank: The formula for calculating weight is ___ = mass × gravitational acceleration.

Answer 8

weight

Question 9

Multiple Choice: Which law explains why seatbelts are important in a car? A) Newton’s First Law B) Newton’s Second Law C) Newton’s Third Law

Answer 9

A) Newton’s First Law

Question 10

What is the relationship between mass and acceleration according to Newton’s Second Law?

Answer 10

They are inversely related; as mass increases, acceleration decreases for a constant force.

Question 11

True or False: Friction opposes the motion of an object and is an example of a force acting on an object.

Answer 11

True

Question 12

Fill in the blank: An object in free fall accelerates at ___ m/s² due to gravity.

Answer 12

9.81

Question 13

Multiple Choice: Which of the following scenarios illustrates Newton’s Third Law? A) A book resting on a table B) A swimmer pushing water backwards C) A car speeding up

Answer 13

B) A swimmer pushing water backwards

Question 14

What is inertia?

Answer 14

The resistance of any physical object to any change in its velocity.

Question 15

True or False: An object will continue moving indefinitely unless a force acts to stop it.

Answer 15

True

Question 16

Fill in the blank: The measure of an object’s mass is a measure of its ___ to change its state of motion.

Answer 16

inertia

Question 17

Multiple Choice: What does the term ‘net force’ refer to? A) The total force acting on an object B) The force of gravity C) The force applied by a person

Answer 17

A) The total force acting on an object

Question 18

What is the effect of balanced forces on an object?

Answer 18

The object remains at rest or continues to move at a constant velocity.

Question 19

True or False: The greater the mass of an object, the greater the force needed to accelerate it.

Answer 19

True

Question 20

Fill in the blank: The law that governs the motion of planets around the sun is based on ___’s laws.

Answer 20

Newton

Question 21

Multiple Choice: Which scenario is an example of an unbalanced force? A) A car driving at constant speed B) A ball rolling to a stop C) A person pushing a stationary box

Answer 21

C) A person pushing a stationary box

Question 22

What is the formula for calculating acceleration?

Answer 22

Acceleration = (Final velocity - Initial velocity) / Time

Question 23

True or False: A larger force results in a larger acceleration for the same mass.

Answer 23

True

Question 24

Fill in the blank: An object experiencing a net force of zero is in a state of ___ motion.

Answer 24

constant

Question 25

Multiple Choice: What type of motion occurs when forces are balanced? A) Accelerated motion B) Constant velocity C) Decelerated motion

Answer 25

B) Constant velocity
