It is easier to catch, a table tennis ball than a cricket ball even when both are moving with same velocity. Why?

There is a tennis ball and a cricket ball of equal volume. Which one has greater inertia and why?

From the top of a tower 100m in height, a ball is dropped and at the same time another ball is projected vertically upwards from the ground with a velocity of 25ms^-1 . Find when and where two balls will meet.

What will be the wavelength of a ball of mass 0.1 kg moving with a velocity of 10 ms^-1 ?

Take a table - tennis ball and make three slits into it. put semicircular fins cut out of a metal sheet into these slits. Pivot the tennis ball on an axle through its centre with a straight metal wire fixed to a rigid support. Now connect a cycle dynamo to this. connect a bulb in series. Direct a jet of water or steam produced in a pressure cooker at the fins. What do you observe ?

A steel ball of radius 2cm is initially at rest.It is stuck head on by another steel ball of radius 4cm moving with a velocity of 0.72ms^-1.Assuming that the collosion in completely inceelastic.Calculate the velocity of the balls after collision.

A ball falls under gravity from a height of 10m with an initial velocity. It collides with the ground,loses 50% of its engery and then rises to the same height.Find the initial velocity.

Explain why A spinning cricket ball in air does not follow a parabolic trajectory.

Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the same mass moving initially with a speed VL If the collision is elastic, which of the following figure is a possible result after collision?

A ball is dropped from the top of a tower. One second later another ball is thrown downwards with a velocity of 15ms^-1 . When and how far below the top will the second stone overtake the first?

When a ball hits a wall with a velocity of 50m/s and bounces back with the same speed, what is the change in velocity of the ball?
