Class 11 Physics1)______ is required to keep a body in motion.
External force
Class 11 Physics2)The law of inertia was given by
Galileo
Class 11 Physics3)Every body continues to be in its state of rest or of uniform motion in a straight line unless compelled by some external force to act otherwise. This is the
Both a and b
Class 11 Physics4)A body at rest continues to remain at rest and a body in motion continues to move with uniform velocity only if
Net external force is zero
Class 11 Physics5)Inertia is nothing but the
Resistance to change
Class 11 Physics6)If the net external force on a body is zero then it’s
Acceleration is zero
Class 11 Physics7)Acceleration can be non zero only if there is
A net external force on the body
Class 11 Physics8)The momentum of the body is the product of
Mass and velocity
Class 11 Physics9)Momentum is the
Vector quantity
Class 11 Physics10)The greater the rate of change of momentum
Greater is the force
