If a body is at rest, it experiences no acceleration. From what frame of reference are you observing the object? You are in a closed elevator in freefall toward earth. You have a tennis ball with you, hanging freely and motionless in front of you (disregarding the drag from air). From your frame of reference it is motionless. I am observing you and the tennis ball from the earth's surface. From my frame of reference, you and the ball are accelerating at 9.8 meters per second per second. Neither of us is wrong. But it won't go so well for you and the ball unless I beam you out, which I surely do.

When forces are balanced compare the acceleration of an object at rest and an object in motion?
An object at rest has zero acceleration. If the set of forces acting on a moving object is balanced, then the moving object also has zero acceleration.
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.
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.
Describe the motion of a person in terms of acceleration?
If the person is walking, after electric impulses tell your feet to move, muscles contract. Your feet, relative to the floor accelerate the rest of your body ahead of them, by means of friction. Too much acceleration can crush a person though, something like 12g?
Can a body at rest have acceleration?
No a boday while rest cannot be in acceleration because of the momentum of the body ...........................
What will be the acceleration of a body at rest?
zero
What is the acceleration for a body at rest?
Zero.
Can a body have an acceleration when it is momentarily at rest?
no
Can a body have acceleration while at rest give example?
a body projected upward is in rest at the top most point, but acceleration is not zero
what is the value of acceleration for a body at rest?
Zero
What is the value of acceleration of a body at rest?
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
Can a body have acceleration while at rest?
yes!A2. The real problem is deciding when a body is at rest - or is it just the rest of the universe that is moving?
Can a body at rest have an accleration?
acceleration is a relative quantity . state of rest or motion is also relative . if two body is in rest or moving with same velocity and having same acceleration then one is in state of rest with respect to other . suppose a person sitting in a train then he is in rest with respect to train but he is moving with the acceleration of train with respect to the ground.
What is the acceleration of a body which starts from rest and travels 87.5 m in 5 seconds?
distance = 1/2 acceleration x time squared; acceleration is 7 m/s/s
Can balance force bring a body to rest?
Balanced forces cannot bring a body to rest. Balanced forces can act on a body which is already at rest or in motion but equal forces cannot change a bodies acceleration, kinetic energy or momentum.
