# Does weight change while accelerating?

## Does weight change while accelerating?

The “weight” of an object based on the definition of “mass * gravity” means that the weight of an object does not change when accelerating.

How does weight affect acceleration?

Engineers will often talk of “power to weight ratio” – because in the early phase of having enough grip this determines acceleration. As the acceleration is slower with a heavier car of the same power, you have to accelerate for longer (more time) to cover the same distance so you use more fuel.

### How much does weight reduction affect acceleration?

A general rule of thumb is for every 10 percent reduction in weight has a comparable 10 percent reduction in the force required to accelerate or decelerate an object.

Does more weight mean more acceleration?

No, because when an object is more massive, the object accelerates slower. If you double the mass of an object, you need twice the amount of force to accelerate it at the same rate.

#### Does reducing weight increase HP?

As you can see from this math, this is why losing weight is rarely as useful as gaining horsepower, or at least, horsepower gain is significantly more practical and cost effective than weight loss in a production car.

What is acceleration equal to?

Acceleration is the change in velocity during a given period of time. At constant velocity acceleration is equal to zero. Slowing down is called negative acceleration or deceleration.

## What is required to cause acceleration?

An object will continue in its state of motion unless an unbalanced force is acting on it. An object’s resistance to change in motion is only dependent on its MASS. MASS. An unbalanced force (or non-zero net force) is needed to cause acceleration.

Do heavier objects slide faster?

So they will not cancel each other. There will be a resultant force which will be proportional to the mass of the object. Hence an object with greater mass feels greater force than the other one. So even if the slope is same for both objects, a massive object moves faster through the slope than a less mass object.
