Answer 2

If a mass of an object is $6$ kg and its velocity is $1$ $\frac{m}{s}$ then its kinetic energy is $3J.$

Explanation:

Given:

Mass of an object $(m)$ $= 6kg$

Velocity $(v)$ $=1\frac{m}{s}$

To find:

The Kinetic energy of an object$(KE)$.

Solution:

Kinetic energy $(KE)= \frac{1}{2} mv^{2}$

Here $m=6kg, v=1\frac{m}{s}$

⇒ $\frac{1}{2}$ × $6$× $1^{2}$

⇒ $3J$

So the final answer is $3J$.

If we want to solve this question, first we have to know the kinetic energy concept.

Kinetic energy:

• Kinetic energy is the energy of an object in motion. It provides information about how the mass of an object influences its velocity.

Kinetic energy formula:

• The kinetic energy formula defines the relationship between the mass of an object and its velocity. The kinetic energy equation is as follows:
• $KE=\frac{1}{2}$×$m$×$v^{2}$

Where,

$m-$ mass,

$v^{2}-$velocity.

Kinetic energy units:

The units of kinetic energy are precisely the same as for any other type of energy. The most popular and commonly used kinetic energy units are,

• Joule $(J),$

• Foot-pound$(ft.lb)$

• Electronvolt $(eV),$

• Calorie $(cal),$

• Watt-hour $(Wh)$

Answer:

Hence the kinetic energy of an object is $3J.$
