Can an object maintains uniform velocity then net force acting on it is not zero?
To answer your title question, if an object is moving with a constant velocity then the net force is 0. However, this does not mean that there are no forces are acting on the object. Because in my textbook it says ” the trolley is given a gentle push down the board until it begins to move with uniform velocity.”
What is the force on a body when it moves with uniform motion?
If a body moves with uniform velocity , the acceleration of body is zero . ∴ net force acting on body is zero .
What is the net force on a body moving with uniform speed?
As the body is moving with a uniform velocity, it’s acceleration is zero. Force acting on the body F = ma, where m is the mass and a is the acceleration. Since the acceleration is zero, the net force acting on the body is zero.
Do we require a force to keep a body moving with a uniform velocity justify?
A continuous supply of force is needed to keep a body in uniform motion because when a constant force is applied on a body then the acceleration is constant and the body remains in uniform motion.
Is it really necessary to apply force to make a body to move?
Yes, it is really necessary to apply force to make a body to move. Existence of the motion of a body is completely dependent on the applied force on that object. So, Newton’s first law of motion also supports the given statement and that’s why we can easily say that the given statement is true.
Can a body have constant speed but varying velocity justify?
Can A Body Have A Constant Speed And Still Have A Varying Velocity? Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.
Is decreasing acceleration same as retardation?
Retardation is acceleration with a negative sign. Or the negative value of acceleration shows that the velocity of a body is decreasing….Thank you.

What is acceleration of retardation?
Retardation is just the opposite of acceleration or the decrease of velocity per unit of time. Acceleration can be positive(+),0,or negative(-). Negative of acceleration is known as retardation. Negative Acceleration is called Retardation, or Deceleration.
