A body of mass "2kg" is moving with a constant velocity of "5ms-1." What is the force acting on it?
Answers
Answer:
Since Acceleration is zero, Force acting on the body is also zero.
Explanation:
Given Data :
The velocity of the body (v) = 5 m/s
Body's mass (m) = 2 kg.
It is mentioned that the body was moving with a constant velocity. This means that the initial and final velocities are the same.
The acceleration of a body is the measure of the change in the velocity with time.
Since the initial and final velocities are the same, the acceleration of the body is zero.
According to the second law of Newton,
Force is the product of mass and acceleration if the mass is constant.
That is, Force (F) = Mass (m) × Acceleration (a)
So, F = ma
Since Acceleration is zero, Force acting on the body is also zero.

A body of mass 2 kg moving at a constant speed of 5 m/s experiences no force.
According to Newton's first law of motion, a body will continue to move at a constant speed until it is affected by an outside force. There is no net force acting on the body of mass 2 kg in this situation because it is moving at a constant speed of 5 m/s.
The force acting on a body can be determined using the formula for Newton's second law of motion, which is given as:
Force = mass × acceleration
The force acting on the body is zero because there is no acceleration because the body's velocity is constant. we can express it as:
Force = 2 kg × 0 m/s2 = 0 N
The force of inertia and the force acting upon it are both equal, preventing any kind of acceleration.
