There are many types of forces such as lift, gravity, buoyancy. But, there are many different ways you can find out the amout of force is needed to in order to move a object or that if you want to calculate the gravity on a object being oulled down by the force.
So, What is a force? Well, a force is a push or a pull that acts on a object. These can be measured in newtons. The word "Newton" comes from the name of the scientist who discovered the force called gravity, his name was Sir Isaac Newton. The history was that Sir Isaac Newton was sitting under an apple tree and that an apple had fallen from the apple tree, so Isaac Newton had realised something must have made apple drop. Types of forces! Gravity
There are as you know many types of forces. The most commonly known force is gravity, gravity is the force that keeps all objects on the ground. There is a way to calculate the amount of force acting on an object by multiplying the mass of an object and the the strength of earth's gravitational field. Buoyancy
Buoyancy is the tendency of an object, eg. a marble, and if its mass will make it either sink more or rise or maybe just float in the middle of a volume of water. This is known as the Buoyant force. If a object were to rise an a fluid the characteristics of the object would most likely be light,(depending on the fluid), and sometimes depending on size. Drag
This force is aligned with the airflow's direction, this force opposes thrust. This force is how the aircrafts fly.
Forces: formulas.
To find out how much the gravity is acting on an object you will multiply the mass by 9.8, after that you will find out.
Mass vs weight.
Now, a lot of people get confused between mass and the weight. Well, the definition of both words seem very similar, but in science weight means the measurement of the pull of gravity on a object, while mass is the amount of matter in the object.
