Balanced forces that net to zero cause no change in an object motion.
what causes the motion of objects
Interaction between objects that causes a change in motion.
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.
I think this question is not phrased very well. Any force can change objects velocity (speed+direction). If fact that is the definition of the force - F=ma any force, by definition itself, can change objects velocity. Maybe you meant what force can change objects direction of motion? In that case - any force that has a different direction (not the same as direction of motion) Any force can change an object's motion.
The term is inertia. It is the property of matter that causes objects to resist changes in their state of motion.
Velocity is a change in an object's motion OR direction of motion.
FRiction
The change in an objects position is called motion.
Forces can change the motion of objects by causing them to speed up, slow down, change direction, or deform. This change in motion is governed by Newton's laws of motion, which describe how forces interact with objects to cause them to accelerate or decelerate.
A force is a push or pull on an object that can cause a change in its motion or shape. It is measured in units called newtons and can be exerted by objects or fields, such as gravity or magnetism.
FRiction
Yes, the tendency of an object to resist a change in its motion is known as inertia, which is a fundamental property of matter. Inertia causes objects to stay at rest or in motion unless acted upon by an external force.
