What is horizontal acceleration?
It is acceleration in the horizontal direction. This would happen as a result of a net horizontal force acting on a body.
Can direction of velocity of a body change when its acceleration is constant?
Yes, the direction of velocity of a body can change even when its acceleration is constant. This can happen if the acceleration and initial velocity of the body are not aligned in the same direction. The body will still experience a change in velocity due to the constant acceleration, which can lead to a change in direction.
Why is the velocity of accelerated body may be zero?
The velocity of an accelerated body may be zero when it temporarily stops moving at a specific point during its acceleration process. This can happen if the body changes direction or experiences a deceleration that causes its velocity to drop to zero before changing again to increase its velocity in the opposite direction.
When is the acceleration of a body is positive?
A body's acceleration is positive when its velocity is increasing over time. This can happen when the body is speeding up in the same direction as its velocity, or when it is slowing down in the opposite direction of its velocity. Both scenarios result in a positive acceleration value.
What would happen if the nervous system of the human body stops working?
The end result would be death.
How will the weight of a man be affected if the earth stops spinning about it axis suddenely?
When the earth stops spinnig there will be no centripetal acceleration and will be no gravity.therefore g=0. since w=mg w=m(0) w=o there will be no weight of a body if earth sudddenly stops spinning
Why do you feel a jerk in an elevator when it starts and also when it stops its motion?
When an elevator starts or stops, there is a change in acceleration which causes a shift in forces acting on your body. This sudden change can make you feel a jerk as your body adjusts to the new motion. It's similar to the sensation you feel when a car accelerates or decelerates quickly.
If a body is acted by a constant force the body will have uniform?
"acceleration"
What happens to the reading on the scale when the elevator stops moving?
When the elevator stops moving, the reading on the scale will briefly increase before returning to the original reading. This is due to the inertia acting on the person's body and affecting the scale reading as the elevator decelerates.
Can a body have zero velocity and still acceleration give examples?
Yes, a body can have zero velocity and still have acceleration. For example, when a car is at a complete stop but then accelerates to start moving, it has zero velocity at the moment before acceleration kicks in. Another example is when an object reaches the peak of its motion and momentarily stops before accelerating back downwards due to gravity.
When a body has velocity no constant has acceleration or no?
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
What is the acceleration of mass?
force acting on unit mass of body is the acceleration of that body.
