Q 01 / 24
Force is required to change the state of motion of a body.
Q 02 / 24
A body at rest will always remain at rest even if an external force is applied.
Q 03 / 24
Inertia is the tendency of a body to oppose changes in its state of motion.
Q 04 / 24
Newton’s First Law of Motion is also called the Law of Inertia.
Q 05 / 24
If no force acts on a body, it will eventually come to rest.
Q 06 / 24
Force is directly proportional to the rate of change of momentum.
Q 07 / 24
Impulse is equal to the change in momentum of a body.
Q 08 / 24
The SI unit of force is Joule.
Q 09 / 24
1 Newton force is that which produces an acceleration of 1 m/s² in a body of mass 1 kg.
Q 10 / 24
Momentum of a body depends only on its velocity.
Q 11 / 24
Every action has an equal and opposite reaction.
Q 12 / 24
Action and reaction forces act on the same body.
Q 13 / 24
When a gun is fired, the backward recoil is an example of Newton’s Third Law.
Q 14 / 24
Seat belts are used in cars to reduce the effect of inertia during sudden braking.
Q 15 / 24
A ball moving on a frictionless surface will stop after some time on its own.
Q 16 / 24
Walking is possible because of Newton’s Third Law of Motion.
Q 17 / 24
The momentum of an isolated system is always conserved.
Q 18 / 24
If two bodies collide, the total momentum before and after collision is the same (in absence of external force).
Q 19 / 24
In a collision, individual momentum of each body always remains constant.
Q 20 / 24
Acceleration produced in a body is inversely proportional to its mass.
Q 21 / 24
Force has both magnitude and direction.
Q 22 / 24
Heavier objects have less inertia than lighter ones.
Q 23 / 24
Newton’s Laws of Motion are applicable only to moving objects, not to objects at rest.
Q 24 / 24
Friction always opposes the relative motion of surfaces in contact.
