Inertia is the property of a body which preserves its state of motion or uniform motion in a straight line. The following factors tell me about inertia.
I. Greater the mass of a body, greater is its inertia.
II. Greater the inertia of a body, the less will be the acceleration produced by a given force.
III. The law of inertia is the same as Newton's first law of motion.
Which combination is true?
A block is moved from rest through a distance of 4m along a straight line path.The mass of the block is 5 kg,and the force acting on it is 20 N.If the kinetic energy acquired by the block be 40J,at what angle to the path the force is acting:
What is the momentum of an object of mass $m$, moving with a velocity $v$?
A bullet of mass 40 g moving with a speed of $90 ms^{-1}$ enters a heavy wooden block and is stopped after a distance of 60 cm. The average resistance force exerted by the block on the bullet is
Force is directly proportional to
Which has a greater momentum, an elephant at rest or an ant in motion?
$SI$ units of momentum is _____
The SI unit of linear momentum is $kg \ m/s^{-1}$.
If the same force is applied on two bodies of different masses for the same time, then the change produced in the momentum of the two bodies is also same .
Momentum is a measure of quantity of motion.
