If you are at rest do you have momentum?
The momentum of a body is defined as the product of is mas and velocity. Momentum = Mass x Velocity. If a body is at rest then obviously its velocity is zero. Therefore, its momentum also becomes zero.
Is the net force acting on a body is zero will the velocity be zero?
No, The velocity CHANGE will be zero
Can a body have accerlation butb still have zero velocity?
Yes, it is possible. When a body thrown upward (from the surface of Earth or any other planet but with velocity small enough not to overcome the gravity) and reaches its maximum elevation its velocity is zero but the acceleration is g (due to gravity).
What is the acceleratipn of a body with uniform velocity and why?
The acceleratipn of a body with uniform velocity is zero. Acceleratipn is the time rate of change of velocity. If the velocity is uniform, then its time rate of change is zero.
What is the difference between rest and equilibrium?
Velocity of body and acceleration of body is zero implies body is at rest Acceleration of body is zero implies it is in a state of equilibrium Body in equilibrium can have non zero velocity
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.
When a body has constnat velocity what is the acceleration?
The acceleration is zero for a body having constant velocity.
Can a body have without velocity?
Yes, but it will have a non-zero velocity afterwards.
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.
Could the body's velocity be zero?
if it is not moving
What does it mean for a body to have zero acceleration?
The velocity of the body does not change.
An a body more with constant acceleration but with zero velocityif yeswhy?
No. Well, such a body can have zero velocity for a brief instant, but it won't stay at such a velocity, because "acceleration" implies that the velocity changes.
