What is the net force acting on a body of mass 1kg moving with uniform velocity 5m/s ?

Question

Answer

Since velocity of object is uniform.
This means acceleration is zero.
So, net force as per formula- F=ma
F=0 ; a=0

Answer

The force will be zero.As the formula for force is mass × acceleration,we need to find acceleration first.Now, as the object is moving with uniform velocity ,the acceleration would be 0.So,f = m×a     f = 1×0        =0

Answer

When velocity is uniform then the acceleration will be zero . So f = ma then net force is zero.

Answer

Ans is 0

Answer

0 is the correct answer

Answer

Net Force on a Body

The net force acting on a body is the vector sum of all the individual forces acting on it. In this case, we have a body with a mass of 1kg moving with a uniform velocity of 5m/s. To determine the net force acting on the body, we need to consider the forces acting on it.

Forces Acting on the Body

In this scenario, there are two main forces acting on the body:

1. Gravity: The force of gravity acts on the body due to its mass. This force can be calculated using the formula F = mg, where F is the force, m is the mass, and g is the acceleration due to gravity (approximately 9.8m/s^2). Since the body is moving horizontally, the force of gravity does not affect its velocity and only acts vertically downwards.

2. Friction: If the body is moving on a surface, there may be a frictional force opposing its motion. However, in this scenario, it is not mentioned whether the body is moving on a surface or if there is any friction present. Therefore, for simplicity, let's assume there is no friction acting on the body.

Calculating Net Force

Since there is no friction acting on the body, the net force is solely due to the force of gravity. As mentioned earlier, the force of gravity acts vertically downwards. However, since the body is moving with a uniform velocity horizontally, the net force in the vertical direction is zero.

Hence, the net force acting on the body is zero Newtons.

Conclusion

In summary, if a 1kg body is moving with a uniform velocity of 5m/s and there is no friction acting on it, the net force acting on the body is zero Newtons. The force of gravity acts vertically downwards but does not affect the horizontal motion of the body.
