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.
Why is acceleration zero when the body is moving with a constant velocity?
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
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.
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
If an object is moving at unifrom acceleration what is its velocity?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.
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..
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.
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.
When a body moving with uniform and negative acceleration?
When the body is in simple hermonic motion
A body is moving with uniform velocity what will be its accelerationshow?
Acceleration is (delta velocity) / (delta time), that is, change in velocity per time unit. In this case, since the velocity doesn't change, the acceleration is 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.
What is the acceleratipn of a body with uniform velocity and why?
The acceleration of a body with uniform velocity is zero because acceleration is the rate of change of velocity. If the velocity is constant, then there is no change in velocity over time, so the acceleration is zero.
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).
When a body has uniform velocity?
When a body has uniform velocity, it is moving in a straight line at a constant speed. This means that the magnitude and direction of its velocity remain constant over time. uniform velocity implies no acceleration present in the motion of the body.
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.
What will be the body said ----- velocities when average and instantaneous velocities are equal?
When the average velocity of a body is equal to its instantaneous velocity, it means that the body is moving at a constant speed in a straight line. This indicates that the body's motion is uniform, with no acceleration or deceleration occurring.
