Question Text
Question 1 :
(1) : When a rigid body is rotating about its own axis, all particles of that body have the same angular velocity.<br/> (2) : All particles of the body have the same time period.<br/>
Question 3 :
Uniform circular motion is called continuously accelerated motion mainly because its :
Question 4 :
The velocity of a body depends on time according to the equation v=$\frac{t^2}{10} + 20$. The body is undergoing
Question 5 :
A force of $100\ N$ acting on a body for $5$ second gives it a velocity of $20\ m\ s^{-1}$. Calculate the mass of the body.
Question 6 :
Circular Motion can be an example of periodic motion. State whether the given statement is True or False.
Question 8 :
The average acceleration vector for a particle having a uniform circular motion in one complete revolution.
Question 9 :
A car accelerates on a horizontal road due to the force exerted by
Question 10 :
A cart is released from rest at the top of a long ramp at time $t = 0$ seconds and moves down the ramp at a constant acceleration rate. At a time of t, the cart has reached a speed of $2 m/s$. How fast will the cart be moving at the time of $3t$?
