A body of mass $m_{1}$ collides elastically with another body of mass $m_{2}$ at rest. If the velocity of $m_{1}$ after collision becomes $ 2/3 $ times its initial velocity, the ratio of their masses, is
A ball impinges directly on a similar ball at rest. The first ball is brought to rest by the impact. If half of the kinetic energy is lost by impact, the value of coefficient of restitution is
If the linear momentum is increased by $50\%$, then kinetic energy will increase by
A string $0.5\, m$ long is used to whirl a $1\,kg$ stone in a vertical circle at a uniform velocity of $5 \,m \,s^{-1}$. What is the tension in the string when the stone is at the top of the circle?
A particle moves along a curve of unknown shape but magnitude offeree $F$ is constant and always acts along tangent to the curve. Then,
$KE$ is conserved at every instant of elastic collision. No deformation of matter occurs in elastic collision.
A block of mass $10\, kg$ is moving in $x$-direction with a constant speed of $10\, m / s$. It is subjected to a retarding force $F=-0.1 \times J / m$ during its travel from $x=20\, m$ to $x=30\, m$. Its final kinetic energy will be :
A bullet is fired from a rifle and the rifle recoils. Kinetic energy of rifle is
A neutron makes a head-on elastic collision with a stationary deuteron. The fractional energy loss of the neutron in the collision is
In an elastic collision of two billiard balls, the total kinetic energy is conserved during the short time of oscillation of the balls (i.e. when they are in contact). Energy spent against friction does not follow the law of conservation of energy.
Work done in uniform circular motion is zero. Force is always directed along displacement.
Centripetal force does no work. Force and displacement are perpendicular to each other.
A body of mass $M$ moving with velocity $V$ explodes into two equal parts. If one comes to rest and the other body moves with velocity $v$, what would be the value of $v$ ?
A body of mass $5\, kg$ has momentum of $10\, kg\, m / s$. When a force of $0.2\, N$ is applied on it for $10$ seconds, what is the change in its kinetic energy?
A particle of mass $ m $ moving with velocity $ v $ collides with a stationary particle of mass $ 2m $ . The speed of the system, will be:
Which of the following is a non-conservative force?
Kinetic energy, with any reference, must be
