an unbalanced force
Issac Newton.
The concept related to the amount of force needed to change an object's motion is inertia. Inertia is the tendency of an object to resist changes in its velocity. Objects with more mass have greater inertia and require more force to change their motion.
Velocity is a change in an object's motion OR direction of motion.
The change in an objects position is called motion.
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 Reference Point A reference point is needed to determine if an object is in motion.
Objects in motion continuously change position.To change direction, a force needs to act upon them.
uniform motion
All objects resist a change in motion due to inertia, which is the tendency of an object to maintain its current state of motion. This resistance is based on Newton's first law of motion. Objects with more mass have more inertia and thus require more force to change their motion.
