## Why do heavier things accelerate faster?

Acceleration of Falling Objects Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

### Will heavier object accelerate more than a lighter one during free fall?

No, because acceleration due to gravity (g) does not depend on the body’s mass. Thus, bodies of different mass accelerate towards the earth with same acceleration.

**How does mass affect force and acceleration?**

The relationship between mass and acceleration is different. It is an inverse relationship. The greater the mass of an object, the less it will accelerate when a given force is applied. For example, doubling the mass of an object results in only half as much acceleration for the same amount of force.

**Is a heavier or lighter car faster?**

It’s clear that a lighter car requires less force to accelerate than a heavier one. With a heavier car of the same power you have to accelerate for longer to cover the same distance so you use more fuel.

## Do heavier objects have more friction?

An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface and the light object.

### Do heavier objects have more force?

Because the downward force on an object is equal to its mass multiplied by g, heavier objects have a greater downward force. Heavier objects, however, also have more inertia, which means they resist moving more than lighter objects do, and so heaver objects need more force to get them going at the same rate.

**What is the difference between mass and weight of an object?**

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity (g).

**Why is a heavier object harder to accelerate?**

The reason that a heavier object does not fall faster even though there is more gravitational force on it is because it has more mass, and more energy is required to accelerate the greater mass. A small mass doesn’t need a lot of force on it to accelerate it.

## What makes an object harder to move than a light one?

The greater the weight (or mass) of an object, the more inertia it has. Heavy objects are harder to move than light ones because they have more inertia. Inertia also makes it harder to stop heavy things once they are moving. What makes an object heavier or lighter?

### Why is the force of gravity stronger on heavier objects?

Basically this means that in one second, any object ‘s downward velocity will increase by 9.81 m/s because of gravity. This is just the way gravity works – it accelerates everything at exactly the same rate. What you may be getting confused by is the fact that the force of gravity is stronger on heavier objects than lighter ones.

**How are heavy and light objects reach the ground at the same time?**

In the absence of air friction both heavy and light objects will reach the ground at the same time. Galileo deduced this by devising clever experiments with balls rolling down inclined planes. Newton gave it his blessing by observing that a = F/M, i.e. the acceleration of an object is proportional to the force, F, on it divided by its mass, M.
