# How does a gravity car work?

## How does a gravity car work?

A Gravicar is a vehicle powered by gravitational potential energy that it stores in a 2.5kg mass on a thread which is coupled to the car’s rear axle via a pulley atop a high platform (see figures 1 and 2). As the mass falls the thread, which is wrapped around the axle, turns the wheel and accelerates the car.

### What is a car pulley?

A motor pulley is a type of wheel that is affixed to the engine of an automobile or other vehicle; this wheel is used to guide a timing belt or serpentine belt that helps power peripheral devices in the car such as the air conditioner unit.

What makes a cardboard car go faster?

Reducing weight, minimizing drag, cutting friction and improving nozzle air flow will all help make your balloon car go faster.

Is a car gravitational energy?

A moving car possesses mechanical energy due to its motion (kinetic energy). A moving baseball possesses mechanical energy due to both its high speed (kinetic energy) and its vertical position above the ground (gravitational potential energy).

## What materials are used to make a car?

The automobile industry consumes raw materials from around the world in the production of cars and auto parts. Steel, rubber, plastics and aluminum are four commonly utilized commodities found in cars.

### Is car wheel a pulley?

The drive belt (or “serpentine belt”) on a car, in conjunction with the pulley wheels is a pulley system: The rotation of the engine (which in effect causes the car to go) is also partially harnessed via a pulley system to run a number of other systems in the car.

How does the gravity car work?

I’m in accelerated physics and we just got assigned the gravity car. The way its supposed to work is like this– a weight is supposed to be dropped from a certain height and its supposed to propel the car forward (GPE converted into KE and so on). The car is supposed to travel at least 5 meters and has to travel in a straight line.

What is the acceleration of a gravity car?

The gravity car has a forward acceleration a1 till the load hits the ground. After the load hits the ground and is disconnected from the gravity car, only friction between the axle and wheels faxle will act on the gravity car to decelerate it till it comes to rest. The gravity car has an instantaneous velocity vc in the forward direction.

## How does the distance travelled by the gravity car depend on load?

The distance travelled by the gravity car was found to be proportional to the distance fallen by the load during the same time. The downward acceleration of the load was calculated and found to increase with increase in load.

### What does this hands-on science lesson teach about gravity?

This hands-on science lesson is designed to teach learners with visual impairments about gravity through the use of toy cars. What is the force that pulls the car down the ramp?
