Four Forces
One of the forces is applied force, which means a push/pull that is usually caused by an object/thing or person. I push my toy car away from me, so I'm applying force to my toy car. Another force is gravitational force which means a force that is attracting two objects it is non contact force. I let go of a tennis ball and it's causing gravitational force, it just falls straight to the ground. One other force is normal force which is a force from a surface and is usually pushing the object up. I push my toy car forward and its causing normal force. Lastly another force is tension force which is a pulling force that is in a string, it can also be a rope or chain. I tied my toy car with a string and I'm pulling the string its causing tension force.
Make sure understand that the normal force is the force that keeps your toy car from falling downward!
