The change in an object's motion, is simply force.
The object cannot change motion unless acted upon by an outside force. For example: If I throw a Baseball, it will never stop unless acted upon by gravity (or the outside force). Or the outside force could be it smacking into a wall or your friends head.
A change in speed or direction is caused by a force and is called acceleration.
The reluctance of a body to change its state of motion is termed inertia. The mass associated with this property is called its inertial mass, notably different from gravitational mass, which is responsible for objects with mass experiencing an attractive force between them. The inertial rest mass of an object is what gives it momentum.
Weight
inertia. the more mass an object has, the greater its inertia. what do you call it when an object refuses a object in motion?
Motion is the change of position over time. The rate of change of position is called or speed. Speed combined with its direction is called velocity. The rate of change of velocity is called acceleration. So, motion in which the speed or direction are changing is accelerated motion. The question uses the word cause, which may be confusing. Technically when a force is applied to a mass, there is acceleration. When there is acceleration the velocity changes. If the object was in motion to begin with, it would speed up or slow down or change direction. If the object was at rest, the force would have caused an increase in speed from zero, so it would start moving. Therefore if you think of a causal relationship, it would be more proper to say force causes acceleration, which IS a change in motion. For an example, an easy one is your bicycle. If you pedal, you are applying force. That force cause the bicycle's speed to increase ... acceleration ... and you are in motion. If you apply more force, you will go faster. If you apply the brakes, you will slow down which is also acceleration (because speed is changing). There is only one way to have motion without acceleration and that is to travel at a constant velocity ... constant speed in a straight line. In practice, there is no motion without acceleration for any period of time, because there is always some minute change in speed or direction.
Inertia
Any action that is able to change the motion of a body is called a force. Forces can cause objects to accelerate, decelerate, change direction, or deform.
Inertia
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.
Change in an object's motion refers to any alteration in its velocity or direction of movement. This can be caused by forces acting on the object, such as friction, gravity, or external pushes or pulls. Newton's laws of motion explain how forces affect the motion of objects.
Motion is change of position. but remember both must always be related to some 'datum' position or state of motion.
Any object on which an unbalance force is acting will accelerate - i.e., its velocity will change.
Mass.
Any part of a force that does not act in the direction of an object's motion does not contribute to the object's speed or change its velocity. This component of force perpendicular to the direction of motion only affects the object's direction or causes it to change its path.
Inertia."Objects in motion tend to stay in motion, and objects at rest tend to stay at rest, unless acted on by an outside force."That is a wording of Newton's first law of motion, also known as the law of intertia.
when two bodies change their positions with time, it's termed as motion and if the motion continues it may begin to have velocity,acceleration etc
Yes, this tendency is described by Newton's first law of motion, which states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This property is known as inertia, where objects resist changes in their state of motion.
