That's called a "force".
Inertia is the tendency of an object to resist a change in its motion.
An applied force will change the motion of an object. Such as a thrust, or an impact.
motion
Balanced forces that net to zero cause no change in an object motion.
motion
Balanced forces that net to zero cause no change in an object motion.
Balanced forces that net to zero cause no change in an object motion.
The three forces that causes an object to change its motion are the gravitational force, the normal force and the frictional force.
Applied force to an object causes motion.
A force acting on the body, along its line of motion.
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
Force, which causes acceleration
