If a body is moving with a uniform velocity.what will be its acceleration?
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
If the displacement of a body is proportional to square of time will the body be moving with uniform velocity or uniform acceleration?
Let us suppose that the displacement is given by, x = kt2 , where k is constant of proportionality. Therefore, velocity of the body, v = dx/dt = d(kt2)/dt = 2kt Since, velocity depends on time ,the body is not moving with uniform velocity.... Again, acceleration of the body, a = dv/dt = d(2kt)/dt = 2k As the acceleration is independent of time , the body is moving with uniform acceleration..
Does a body moving with uniform acceleration have momentum?
Yes, a body moving with uniform acceleration has momentum. Momentum is the product of an object's mass and its velocity, and acceleration is the rate of change of velocity. As long as the object is moving and has mass, it will have momentum.
If a body is acted by a constant force the body will have uniform?
"acceleration"
Discuss if a body moving with uniform velocity is in equilibrium?
A body moving with uniform velocity is in equilibrium when it moves with uniform velocity as no acceleration i.e. no net force acts on the body.The sum of all forces must be zero in this case. (To avoid rotation, the sum of all torques must also be zero).

Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
When will you say a body is in uniform acceleration non uniform acceleration?
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
What is the negative acceleration?
Negative acceleration is the state of a body whose velocity in a specified direction is becoming smaller. If you apply the brakes while driving a car, the car (and you) will undergo negative acceleration in the direction in which the car was moving.

Is the statement 'a body moving with uniform speed along a circular path is subjected to uniform acceleration' true or false justify?
This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.
What is the value of acceleration when a body moves uniformly?
When a body moves with uniform, its acceleration is is constant if v(m/s) t(s) a(m/s2) 4 1 0 8 2 4 12 3 4 16 4 4 (8-4/1)=4 12-8/1=4 hence acceleration is constant.
Can an object's acceleration be a negative number?
Yes, an object's acceleration can be a negative number if it is experiencing deceleration or moving in the opposite direction of its positive acceleration. Negative acceleration represents a decrease in velocity over time.
