Question 1
1 / -0

Inertia refers to

A
dullness

B
slow motion

C
ease of motion

D
resistance to change

Solution

Explanation:

Inertia is the resistance of any physical object to any change in its state of motion; this includes changes to its speed, direction, or state of rest. It is the tendency of objects to keep moving in a straight line at constant velocity. Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
Question 2
1 / -0

Force is a

A
quantitative measure of the momentum between two bodies

B
qualitative measure of the momentum of two bodies

C
qualitative measure of the interaction between two bodies

D
quantitative measure of the interaction between two bodies

Solution

Explanation:

Newton's second law of motion gives the quantitative definition of force. The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object
Question 3
1 / -0

force is required

A
only to start a stationary object moving

B
only to stop a moving object

C
to start a stationary object and to stop a moving object

D
only to keep an object moving

Solution

Explanation:

force is required to start a stationary object and to stop a moving object due to inertia. Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. This is also called law of inertia or newton's first law of motion
Question 4
1 / -0

According to first law of motion

A
body acted on by net force moves with constant velocity (which may be zero)

B
body acted on by no net force moves with increasing velocity and negative acceleration

C
body acted on by zero net force moves with non zero acceleration

D
body acted on by no net force moves with constant velocity (which may be zero) and zero acceleration

Solution

Explanation:

If net force act on a body then acceleration of the body will also be zero.Hence velocity will not be changed i.e. it continues in its existing state of rest or uniform motion in a straight line.
Question 5
1 / -0

Force F at a point in space (location of the particle) at a certain instant of time t is

A
related to acceleration a at that point and the same instant.

B
related to acceleration a at that point at next instant.

C
related to acceleration a at previous point at that instant.

D
related to acceleration a at that point at previous instant.

Solution

Explanation:

According to Newton's second law of motion the acceleration of a point mass as produced by a net force is directly proportional to the magnitude of the net force at that point in the same direction as the net force at that instant

F = ma
