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 is constant accelaration?
M/s -1 - For example gravity has a constant acceleration of 9 M/s -1
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 the different between acceleration and decelaration?
one is positive one is negitive.
The term decelaration means?
Acceleration is to speed up. Deceleration is to slow down.
Is decelaration a scalar or vector?
Acceleration is a vector quantity, as it has both magnitude and direction.
Accelaration is a change in what?
it changes the speed
What is the opposite word for accelaration?
decelration
Where to find the decelaration in poptropica?
On the other side of where you give the bag of salt behind the big block of mud
When a object motion changes that is called what?
accelaration?
waht is g?
g is gravitational accelaration
Why accelaration due to gravity on moon is less than accelaration due to gravity on earth?
Because the earth is much more heavier than the moon.
Is accelaration a scalar or a vector?
It's a vector one.
What do you mean by accelaration?
Acceleration is any change in velocity.
What is the accelaration of objects on earth?
9.8m/s^2
