What is the formula of velocity ratio?
Effort force:Load force. For example, if you put in 10 newtons of force and the load force was exerting 5 newtons the velocity ratio would be 2:1
What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
How can you increase the velocity of thre ore?
We can use Newtons 2nd law to figure this out. The formula is Force (Resultant) = Mass x Acceleration. The ores mass is constant. If you use a greater force, working out the formula, the velocity increases.
What is newtons second law of motion formula?
The original formula Force=(mv-mu)/twhere m-mass, v- final velocity, u- initial velocity, t- timeThe derived form Force= mass x acceleration
If the speed of a moving object is doubled the kinetic energy of the object is?
The relation between kinetic energy is proportional to the square of velocity. Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time.
What happen to the braking distance if the speed is doubled and why?
Hi there! Assuming that the deceleration (or negative acceleration, if you will) is constant and the same in both cases, you can use a special kinematic formula to solve the problem. The formula follows: (final velocity)^2 = (initial velocity)^2 + [ 2 * (deceleration) * (braking distance) ] Rearranged to our needs the formula reads: braking distance = [1/2] * -(initial velocity)^2 / (deceleration) * this equation assumes that the final velocity is zero If the initial speed were doubled then the general formula would read: braking distance = 2 * -(initial velocity)^2 / (deceleration) NOTICE that the two equations are the exact same except for the leading coefficients. 1/2 is assocaited with the braking distance of the normal velocity while 2 is assocated with the breaking distance of the doubled velocity. Since 2 is four times larger than 1/2, this leads us to the conclusion that the breaking distance for an object traveling at double a certain velocity would be 4x greater than the breaking distance of the object moving at the "regular" velocity.
How do you change pounds to newtons?
Formula: pounds x 4.448 = newtons
What is the equation to find Newtons?
Also if you mean Newtons in terms of weight the formula is Newtons = Mass * Gravity
What ist the formula fir velocity?
The formula for velocity is (v = d/t) or (velocity = distance/time).
What is the formula to velocity?
Velocity is distance / time
Formula for finging velocity?
velocity is distance/time
What happens when area of contact is increased?
When area of contact increases between two objects, then the pressure applied decreases. Here is the formula: Pressure(Pascals)=Force(newtons)/area(metre2)
