M/s -1 - For example gravity has a constant acceleration of 9 M/s -1
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.
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)
Directly. That's why you can't move a car by blowing on it.
You cannot. You must have distance (or displacement). If you know it is from a standing start then accelaration will do.
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!!
When an object is not accelerating at all. It has constant velocity.
yes and its 9.8m/s2
Accelaration
Directly. (F = m a) If a (acceleration) is a constant then the relationship between farce and mass is constant.
a = (v2-v1)/t if velocity never changes then acceleration is always zero
F = GMm/r2 where G is the gravitational accelaration constant apprximately equal to 6.67 x 10-11
Constant velocity implies zero acceleration, so you would have a horizontal line, identical to the x-axis.
Force is directly proportional to acceleration, so acceleration changes as force changes, whether it increases, decreases, or remains constant.
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
Force = mass x Accelaration
food
it changes the speed
