Inertia of a body depends on 

One kilogram force equals to

To project the rockets which of the following principle(s) is /(are) required?

The resistance of a body to change its state of rest is called

The momentum of a heavy object at rest will be

To produce a displacement ___________ is required

By convention, the clockwise moments are taken as ___________ and the anticlockwise moments are taken as__________.

A man of mass 100 kg has a weight of ___________ at the surface of the Earth

A body changes its state, then it is said to be in ______

Momentum is a ______ quantity.

Bodies of larger mass need greater effort to put them in motion. Why?

A lift is accelerated upward. What is apparent weight of a person inside the lift?

Action and reaction forces do not balance each other. Why?

A boy puts a heavy box of mass M on his head and jumps down from the top of a multistoried building to the ground. How much is the force exerted by the box on his head during his force fall? Does the force of gravity increase during the fall?

Assertion: The value of ‘g’ decreases as height and depth increase from the surface of the Earth.
Reason: ‘g’ depends on the mass of the object and the Earth.
Codes:
a) If both the assertion and the reason are true and the reason is the correct explanation of assertion.
b) If both the assertion and the reason are true, but the reason is not the correct explanation of the assertion.
c) Assertion is true, but the reason is false.
d) Assertion is false, but the reason is true.

Assertion: A rocket moves forward by pushing the surrounding air backwards.
Reason: It drives the necessary thrust to move forward, according to Newton's second law.
Codes:
a) Both assertion and reason are true and reason is correct explanation of assertion
b) Both assertion and reason are true but reason is not the correct explanation of assertion.
c) Assertion is true but reason is false
d) Assertion is false but reason is true

Assertion: No force is required to move a body uniformly along a straight line.
Reason: Because F = ma = m(0) = 0.
Codes:
a) Both assertion and reason are true and reason is correct explanation of assertion
b) Both assertion and reason are true but reason is not the correct explanation of assertion.
c) Assertion is true but reason is false
d) Assertion is false but reason is true

Assertion: The net force acting on a body is zero.
Reason: The body is moving uniformly along a straight line.
Codes:
a) Both assertion and reason are true and reason is correct explanation of assertion
b) Both assertion and reason are true but reason is not the correct explanation of assertion.
c) Assertion is true but reason is false
d) Assertion is false but reason is true

Differentiate mass and weight.

State the principle of moments.

State Newton’s second law.

What is meant by Apparent weight?

A ball of mass 1 kg moving with a speed of 10 ms^-1 rebounds after a perfect elastic collision with the floor. Calculate the change in linear momentum of the ball.

Give the application of torque.

State Newton’s laws of motion?
