Newtons laws

Every object in a state of motion tends to remain the in that state of motion unless an external force is applied to it. For example In order for a plane to remain n flight it requires constant thrust from engines to propel it forward and constant lift generated from the airfoil shape of its wings.

.

For every action there is an equal and opposite reaction. Propellers chew up the air in front of them to generate thrust ( opposite reaction…) they are also shooting the used air out the back.

Acceleration is produced when a force acts on a mass. The greater the mass, the more force needed to accelerate the object
