Applied force
Accerleration
The rate of change in velocity is known as acceleration.
Force
Balanced forces that net to zero cause no change in an object motion.
Pressure could cause objects to deform.
Interaction between objects that causes a change in motion.
what causes the motion of objects
An external force is a force that causes a change in an object's motion by pushing or pulling it in a certain direction. This force can accelerate, decelerate, or change the direction of the object's movement.
applied force
A force, or several forces that don't add up to zero, acting on the object.
The gravitation
Gravity is the force that causes objects to have weight. Gravity is the attraction between two objects with mass, such as the Earth and an object on its surface, that causes objects to be pulled towards each other. The strength of gravity depends on the masses of the objects and the distance between them.
