Yes, a object can still be accelerating when the speed is zero, a classic example of which is throwing a ball straight up in the air, at the top of its trajectory it has an instantaneous velocity of zero while it is still accelerating towards the ground.
Answer #1:
No. Acceleration is defined as a change in velocity, regardless of magnitude or sign.
If an obect has a velocity of 0 m/s, then it's acceleration must also be 0 m/s.
However, an object can have a velocity with zero acceleration if the velocity is
constant.
===========================
Answer #2:
An object can have acceleration and still have zero velocity AT ONE INSTANT of time.
When you toss a ball or a stone upward, it has constant acceleration downward,
due to gravity, as soon as it leaves your hand. It proceeds upward for a while, then
stops and begins to move downward. At the very peak of the arc, at the transition
from upward to downward motion, its velocity is zero.
Same for a pendulum at either end of every swing.
Yes, it can. When an object has constant speed it has no acceleration.
The answer you seek is within you must find it yourself to understand
absolutely. it can change direction. Objects moving in circles are always accelerating
no, but it has Potential energy
An object is not accelerating when it is moving in a straight line at an unchanging speed (which may be zero).
"Terminal Velocity". Usually about 125 mph.
If the force acting upon an object are balanced then the object must not be accelerating
Statinory object can be moved. Moving object can be stopped. Direction of a moving object can be changed.etc.
No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
moving
An object is not accelerating when it is moving in a straight line at an unchanging speed (which may be zero).
No. A nonzero acceleration means that the velocity is changing, so it can only have a 0 velocity at a single point in time, such as when a ball thrown in the air reaches its peak.
The object is slowed,The object is stopped,The object's motion is reversed.
Not accelerating. It could be stationary or moving at a constant speed.
"Terminal Velocity". Usually about 125 mph.
If the force acting upon an object are balanced then the object must not be accelerating
If the object's speed is changing, or it's not moving in a straight line, then it's accelerating.
Statinory object can be moved. Moving object can be stopped. Direction of a moving object can be changed.etc.
You would say that the object in motion is accelerating. Or you can say that the object's velocity is increasing.
No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
i am ten so this will be a wimpy answer. it is an object that has nothing to propel it and therefor it has no acceleration. see wimpy Actually the above is wrong because an object can still be moving but it is accelerating only when there is a change in speed or direction. A car moving at a constant speed of 50 m/h is not accelerating however we can agree that it is still moving.
