Question

If we know the speed and mass of an object, we can find out its kinetic energy.

• A. True
• B. False

Answer 1

The correct option is A True

1. The property by virtue of which a body stays in motion is called kinetic energy.
2. Velocity is the speed of a body in a particular direction. It is a vector quantity.
3. The kinetic energy$\left(k\right)$ of a body can be obtained by the relation $k=\frac{1}{2}m{v}^2$, where $m$is the mass and $v$ is the velocity of the body.

Hence, the given statement is true.
