'Force'.
Remember Newton's three laws of Universal Dynamics.
A body/mass will stationary or in uniform motion unless acted upton by a force.
Force is directly proportional to mass and acceleration
To every force there is an equal and opposite force.
When you multiply an object's mass by its acceleration, you get the force acting on the object, as described by Newton's second law of motion (Force = mass x acceleration). This force determines how the object's motion will change, whether it will speed up, slow down, or change direction.
The moment of inertia of objects is important in the study of rotational motion because it determines how difficult it is to change an object's rotation. Objects with larger moments of inertia require more force to change their rotation, while objects with smaller moments of inertia can rotate more easily. This concept is crucial in understanding how objects move and behave in rotational motion.
The centre of gravity does not, by itself, determine whether an object is at rest or in motion. The location of the centre of gravity, relative to where the object is supported, can contribute one of many forces that can act on the object. And it is is the [vector] sum of these forces which determines whether the object remains at rest or in uniform 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.
The total vector force on an object determines the change in its velocity. That change is also known as acceleration.
The extent of resistance to a change of motion is determined by an objects mass. The mass of the object is measured in kilograms.
When you multiply an object's mass by its acceleration, you get the force acting on the object, as described by Newton's second law of motion (Force = mass x acceleration). This force determines how the object's motion will change, whether it will speed up, slow down, or change direction.

Velocity is a change in an object's motion OR direction of motion.
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.
The total vector force on an object determines the change in its velocity. That change is also known as acceleration.
Acceleration in physics is the rate of change of an object's velocity over time. It measures how quickly an object's speed is changing. Acceleration is directly related to the motion of objects because it determines how fast an object is speeding up or slowing down. Objects with a higher acceleration will change their velocity more rapidly than objects with a lower acceleration.
The motion of objects is influenced by factors such as forces acting upon them, their mass, and the surface friction or resistance that they encounter. These factors can determine whether objects move in a straight line, change direction, speed up, slow down, or come to a stop.
Objects in motion continuously change position.To change direction, a force needs to act upon them.
