Hello, my name is Cameron and I will be talking about forces and force fields!
First off, force means strength or energy was an attribute of physical action or movement.
A force field is a barrier made up of of energy and that could have a positive charge or negative charge.
Any push or pull is a force. When a force is applied to an object, it's motion will change. Forces can act on objects they are in direct contact with, or when they aren't touching.
There are contact forces and non-contact forces. Friction, spring, push of air, and buoyant are all contact forces. Non-contact forces are gravity, electrostatic, and magnetic.
Lastly, to strengthen friction is to change the surface. The second way is to change how hard the surfaces are pushed together. That's it for forces!! See you later!!
