Question 3
 Which of the following combinations is true about the mass of a body according to Newton? Mass is the quantity of matter contained in a body .Mass is represented by the relation, mass= force/ velocity .Mass is always conserved.Mass of a body is the ratio of its weight to the acceleration due to gravity at a particular place.
A
I. II, and III only
B
I. III, and IV only
C
I, II, and IV only
D
I, II, III, and IV
Question 4
 Inertia is the property of a body which preserves its state of rest or uniform motion in a straight line. The following factors tell more about inertia:   Greater the mass of a body , greater is its inertia, Greater the inertia of a body, lesser will be the acceleration produced by a given force. The law of inertia is the same as Newton’s first law of motion.  Which combination is true ?
A
I, II, and III
B
I, and II only
C
I, and III only
D
II, and III only

They will come closer
B
They will go apart
C
There will be no change
D
They will go up
Question 6

A
The kinetic energy of the ball
B
The potential energy of the ball

II only
B
I and II only
C
In all the cases
D

I, II and IV only
C
II, III and IV only
D
I, II, III and IV
