What is the difference between tangential and centripetal acceleration?
Tangential acceleration is the change in speed of an object moving in a circular path, while centripetal acceleration is the acceleration that keeps an object moving in a circular path. Tangential acceleration affects the speed of the object, while centripetal acceleration affects the direction of the object's motion.
If a body is moving with a uniform velocity.what will be its acceleration?
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
What is the difference between tangential acceleration and radial acceleration in the context of circular motion?
Tangential acceleration is the change in speed of an object moving in a circular path, while radial acceleration is the change in direction of the object's velocity. Tangential acceleration affects the object's speed, while radial acceleration affects the object's direction of motion.
Is it possible for a body to have acceleration when moving with constant veloctiy?
No, because acceleration is the rate of change of velocity.
Is it possible when a body to have acceleration when moving constant speed?
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
Why is acceleration of a body moving uniformaly in a circle directed toward the centre?
The acceleration of a body moving uniformly in a circle is directed towards the center because the velocity of the body is constantly changing direction, even though its speed remains constant. This change in direction of the velocity results in a centripetal acceleration that is required to keep the body moving in a circular path.
Does the distance affect the body's acceleration moving in a straight line whose accelerationis constant?
No, distance does not affect the body's acceleration when moving in a straight line with constant acceleration. The acceleration of an object depends only on the force acting on it, not the distance it travels. The acceleration will remain constant unless a different force is applied.
Does a body moving with uniform acceleration have momentum?
Yes, a body moving with uniform acceleration has momentum. Momentum is the product of an object's mass and its velocity, and acceleration is the rate of change of velocity. As long as the object is moving and has mass, it will have momentum.
When can you say that a moving body has diccelerated?
A moving body is decelerating when its velocity is decreasing over time. This can be observed when the speed of the body is decreasing, or when the body is moving in the direction opposite to its initial velocity. Deceleration is the opposite of acceleration, where acceleration is the rate of change of velocity, deceleration is the rate at which the speed decreases.
When a body moving with uniform and negative acceleration?
When the body is in simple hermonic motion
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
