Does a negative acceleration mean an object is slowing down?
An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down.
Can a body have 0 velocity and still be accelerating example?
Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up. At the peak point its velocity becomes 0 but still accelerates due to gravity.
Can a body move with constant acceleration but with zero velocity?
Explanation: There is no such case. An object with a constant acceleration but zero velocity is not possible, because according to the definition of acceleration, acceleration is the rate of change in velocity. If an object is at zero velocity it does mean that it is at rest.
Is it possible for an object to move with constant acceleration but with zero velocity give example?
When an object is thrown upwards, the maximum height velocity of the body is zero, but the constant acceleration due to gravity is still working. (b) The given statement is possible. So when the object in a circular motion, the velocity and accelerations are in a mutually perpendicular direction.
Is it possible to have an object moving with an acceleration but with uniform speed?
Answer: Circular motion is an example of an object which is moving with acceleration but with uniform speed. In case of circular motion, the velocity keeps changing as direction changes( though magnitude remains constant) and hence the object is accelerated but there’s no change in speed( the magnitude).
Is an object moving in a circle accelerating?
A change in direction causes a change in velocity . This is because velocity is a vector quantity – it has an associated direction as well as a magnitude. A change in velocity results in acceleration , so an object moving in a circle is accelerating even though its speed may be constant.
What is acceleration in uniform speed?
Acceleration of a body moving with a uniform velocity = 0.
Can a body move horizontally with acceleration in vertical direction?
Yes, Its possible. A body projected at some angle will have horizontal motion, while Acceleration due to gravity “g” will be acting vertically down. When a body tied with rope moves in a vertical circular path, at the bottom most point velocity is horizontal and acceleration is in the vertical direction.
Does a body have acceleration in the following situation Why?
When an object moves along a circular path,its direction of motion keeps changing continuously. The velocity changes due to continuous change of direction and thus the motion along a circular path is said to accelerated. A body travelling along a circular path with non uniform speed will have acceleration.
Which of the following situations is possible an object can have acceleration but constant velocity?
An object can have acceleration, but constant velocity. The velocity of an object may be zero but acceleration is not zero. Distance and the magnitude of displacement are equal in circular motion. Average speed and the magnitude of average velocity are always equal in circular motion.
Which of the following are possible a body has zero velocity?
Answer Expert Verified When a body is thrown vertically upward in space, then at the highest point, thebody has zero velocity but the acceleration of the body will be equal to theacceleration due to gravity. A body moving horizontally with an acceleration in vertical direction is possible in a projectile motion.
What is acceleration under free fall?
A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). It is known as the acceleration of gravity – the acceleration for any object moving under the sole influence of gravity.
