Describe the motion of a bus whose accelaration is zero but the speed is not zero?

It is slowing down. The bus is not picking up speed--accelerating--and its speed isn't zero, as it is not completely stopped. ------------------------------------------------------------------------------------------------------------ The above answer is incorrect as slowing down indicates a negative acceleration not a zero one. The correct answer is that the bus is at a constant speed - any constant speed.


Class 9 -what is the formulae for finding retardation in physics?

Retardation or deceleration is negative accelaration formula for finding retardation is same as that of accelaration: v-u/t, where v is the final velocity, u is the initial velocity and t is the time taken. eg- a bus is travelling at 20 m/s. Brakes are applied to stop the bus. The total time taken by the bus to stop is 2 s. Find its retardation. ans- v=0; u=20; t=2 accelaration= 0-20/2 a= -10 m's^2 retardation= 10 m/s^2 (because retardation is negative accelaration)


Is accelaration directly proportional or inversely proportional to the force?

Directly. That's why you can't move a car by blowing on it.


How do you find velocity given only the time?

You cannot. You must have distance (or displacement). If you know it is from a standing start then accelaration will do.


What factors are involved in determining stopping distance of a toy car?

arent u a science student? its simple. time,initial velocity,accelaration the formula is; v2=u2+2as here v is final velocity u is innitial velocity a is accelaration s will be3 the stopping distance okkkk!!

What is zero accelaration?

When an object is not accelerating at all. It has constant velocity.


Is accelaration due to gravity is constant?

yes and its 9.8m/s2


How is force related to mass at contant accelaration?

Directly. (F = m a) If a (acceleration) is a constant then the relationship between farce and mass is constant.


What is the accelaration of a car that travels in a straight line at a constant speed?

a = (v2-v1)/t if velocity never changes then acceleration is always zero


What does the graph of accelaration vs.time look like for something going a constant velocity?

Constant velocity implies zero acceleration, so you would have a horizontal line, identical to the x-axis.


Can there be a body moving with constant acceleration but zero velocity. With examples?

since accelaration is the change in velocity of an object per unit time......if velocity is zero then there is no acceleration.its nt possible


What is the conclusion of non accelerated rectilinear motion?

The conclusion of non-accelerated rectilinear motion is that the velocity of the object remains constant over time, with no change in speed or direction. This means that the object moves in a straight line at a constant speed.


Accelaration is a change in what?

it changes the speed


What is the opposite word for accelaration?

decelration


What is an object that continues to move at a constant speed without a force?

An object moving at a constant speed without a force acting on it experiences no acceleration or external influence to change its motion. In the absence of forces like friction or gravity, an object can continue moving at a steady pace indefinitely.


When a object motion changes that is called what?

accelaration?
