Physics Gravity Car


So you all must have heard about gravity. According to Newton, gravity is the force which attracts objects towards them. So earth's gravity is the reason we all can walk on earth's surface because it attracts towards itself.

There is some cool experiment with physics gravitation and one of them is physics gravity car which is a motor-less vehicle which moves with the help of gravity, it converts gravitational potential energy into mechanical energy.

Introduction:

A Gravity car is a motor-less vehicle which moves using the force created due to gravity. It's structure is designed in such a way that, it can move with the help of gravitational forces. 

Principle:

Gravity car moves due to the force created by gravity. In physics gravity car, gravitational potential energy is converted into mechanical energy.

As discussed earlier we know that gravity car moves due to the force created by converting gravitational potential energy into mechanical energy.

Structure of gravity car is in such a way that it uses the energy created by weight and gravity on a car. This gravitation potential energy is converted into mechanical energy which pushes the car in forward direction.

Mechanism:

So how does physics gravity car work ? We all know that it moves due to the force created by the conversion of gravitational potential energy into mechanical energy, but how to do that ? What is the process to convert Gravitational Potential energy into mechanical energy ?

The answers to all of your questions is the structure and design of the physics gravity car. Gravity Car is a motor-less and driver-less car. So there is no one who is actually controlling it or riding it. You will see that gravity is the one who is controlling the speed, acceleration and direction of the force of gravity car.

In design of the Gravity car you will notice that weight on the string which is attached through the pulley and attached to the car. Gravity on weight creates force forward and this is the reason car moves forward, but in the start, you need to provide some force by yourself and afterwards gravity will take care of that. Due to opposing forces such as friction, it will not move more forward and eventually will slow down.

How to make a gravity car ?

You want to make one for yourself, at your home ? We have steps to guide you on how to create a gravity car at your home ?

Materials Required: Disc (for tires), cardboard or wood, string, pulley and a weight.

Step 1: Create a simple model car as shown in the figure below.

Step 2: Attach a pulley with your base.

Step 3: Attach string at one side of the car and put weight on a string going through pulley. As shown in Figure:

So your own homemade gravity car is now ready :). It's simple and fun to play with.

Gravity car race:

This cool science experiment can be used for some fun purpose right ? So we have one method to use physics gravity car to play with.

Creating a different design of gravity car according to you and have fun by racing. It's one of the applications of gravity car.

Gravity racing is interesting where a motor less gravity car is raced down the road either with clock or other competitors.


How to increase the speed of gravity car ?

Answer to this question is simple! Simply add the more mass to the string. Increasing the mass on the string will create more force result in more speed.
