Question

Calculate the kinetic energy of an object of mass 1 kg moving with a speed of 1 m/s. ​

Answer 1

We know,

$\boxed{\bold{\sf{Kinetic \ Energy \ (KE)= \frac{1}{2}mv^2}}}$

Here,

• Mass (m) = 1 kg  

• Speed (v) = 1 m/s

Applying values to the equation:

⇒ KE = 0.5 × 1 × 1²

⇒ KE = 0.5 × 1 × 1

⇒ KE = 0.5 J

$\boxed{\bold{\sf{Kinetic \ Energy \ (KE)= 0.5 \ J}}}$

Answer 2

As per the details provided in the question.

In the above question, we have the details as follow.

The given data is the mass of an object 1 kg.

speed of the object that is velocity 1 m/s.

We have to find the kinetic energy of an object.

Here we have to use the formula of kinetic energy.

Thus, the kinetic energy of an object is as follow,

$K.E=\frac{1}{2} \times m \times v^{2}$

Substituting the given value in the above equation we get,

$K.E=\frac{1}{2}\times 1\times 1^{2} \\K.E=\frac{1}{2} \times 1\\K.E=0.5\times 1\\K.E=0.5J$

Hence the kinetic energy of an object is 0.5J
