Is it possible to have zero velocity and still be accelerating?
Yes, it’s possible to have zero speed while accelerating, but only for an instant.
Acceleration is the rate at which an object’s speed and direction are changing with time, so whenever an object passes through zero speed as it reverses directions it has a non-zero acceleration but a speed of zero..
Is work done if there is no acceleration?
If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that’s not to say that there isn’t work done by individual forces on the object, but the sum is 0 ).
Does constant speed mean no acceleration?
An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. If an object’s velocity is constant, however, its acceleration will be zero. … Since it travels in a straight line, its direction does not change.
What is the force if there is no acceleration?
If there are no forces acting upon the object, then there is no acceleration. If there is no acceleration, then the object will move with a constant velocity. Mathematically, we can look at Newton’s second law and the formula for acceleration. We know that the force is zero.
Can a body have acceleration without velocity give example?
A bode can have acceleration without zero velocity. For eg. when an object is thrown upwards, then at the maximum height, velocity at body is zero at that instant but it has acceleration due to gravity.
Can a body have acceleration without change in velocity explain?
Can a body have acceleration without change in magnitude of velocity ? … So yes, a body can have acceleration even if it has constant magnitude.In this case the direction of motion may change. Ex circular motion ,the direction continuously changes.It is accelerated motion even if the speed is constant.
Is it possible to have no acceleration and still be moving?
Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity. For example, a puck sliding along a horizontal plane of ice after being hit with a hockey stick.
Can a body have acceleration at rest?
Finding the acceleration Thus, even though the velocity of an object at rest must be zero, acceleration can clearly be non-zero for objects at rest. A particle that is thrown vertically upwards stops momentarily at the highest point of motion.
Can a body have constant velocity and varying speed?
No, a body can not have its velocity constant, while its speed varies. Rather, it can have its speed constant and its velocity varying. For example in a uniform circular motion.
Can a body have acceleration with constant velocity?
The velocity vector is constant in magnitude but changing in direction. … For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.
