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 equation for gravitational force?
F = GMm/r2 where G is the gravitational accelaration constant apprximately equal to 6.67 x 10-11
What is the formula for input force?
Force = mass x Accelaration
What increases as force increases and mass stays the same?
The equation for force is F = M x A F = Force, M = Mass, A = Acceleration Based on the equation, in order for force to increase, and mass stay the same, you will have to increase the accelaration of the object in motion.
What is the unit for accelaration?
food
Accelaration is a change in what?
it changes the speed
What is the opposite word for accelaration?
decelration
When a body move upward in a lift what will be effect on its weight?
Yes,there is a affect if it moves in a accelaration or deaccelaration.Thats because gravitation accelaration is changed.
When a object motion changes that is called what?
accelaration?
What meaning of accelaration?
To boost or to speed up!
What the meaning of accelaration?
To boost or to speed up!
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.
