Question 1

Select the correct statements related to First Law of Motion?

1). The first law of motion is also known as the Law of Inertia.

2). According to this law, anybody tends to stay in its state of uniform motion or state of rest until and unless an external force is applied to it. Some of all the forces acting on the body are zero, and the object remains unaccelerated.

3). This law introduces us to a new concept called inertia.

Question 2

Isaac Newton, in 1687, presented the three laws of motion in his book Philosophiae Naturalis Principia Mathematica, commonly known as the ....

Question 3

Consider the following statements:

Statement I : Inertia: It is a property of a body by virtue of which the body stays in its state of rest or of uniform motion. It is directly proportional to the mass of the body.

Statement II : There are three types of inertia: Inertia of Rest, Inertia of direction, and the Inertia of Uniform Motion.

Question 4

Choose the correct statements ?

1). The property of a moving body defined by the product of mass and velocity of the moving body is known as the momentum of that body.

2). Impulse is a quantity that describes the effect of a net force acting on an object.

Question 5

Consider the following statements:

Statement I : According to the second law of motion, the rate of change of momentum of a body is directly proportional to the applied force on the body in the direction of the force.

Statement II : The second law of motion introduces us to a new quantity called momentum.
