A body of mass 2 kg is moving along a straight path with the velocity of 2 m/s. The external force acting on the body is _____
Answers
The external force acting on the body is 0 N.
Explanation:
Force is defined as the product of mass and acceleration of the body. It is represented as F. SI units of mass and acceleration are kilogram and meter-per second respectively. Hence the SI unit of force is kilo-meter per second. This is also called Newton (N).
Here, we've been given that, A body of mass 2 kg is moving along a straight path with the velocity of 2 m/s.
With this information, we've been asked to find out the external force acting on the body.
Since, the velocity is constant, so the acceleration will be 0 m/s².
We can find out the force applied by the body, by simply using second law of Newton.
Second law of Newton defined as the product of mass and acceleration is equal to the force. In mathematical term it would be like this;
→ F = ma
By substituting all the available values in the formula, we get:
→ F = 2 * 0
→ F = 0 N
Hence, the external force acting on the body is 0 N.
