The objects in motion are the ball and the bat. The ball has no guarantee of going in a straight line because it depends on the pitch and the wind and the bat goes from …side to side when the player swings it to hit the ball.
An object is deemed to be moving, or in motion, when there is a change in position of an object compared to a stationary object.
the speed increase
That is the object's 'speed'.
Inertia is the tendency of an object to resist a change in its motion.
This depends on the momentum of the object, which is the product of mass and the velocity of that object. The more the momentum the more tendency the object has to remain in m…otion.
If the force moving an object point at least partially in the opposite direction of the object motion the work is considered to be?
when the object is at rest
An object at rest has constant velocity of zero, thus still uniform motion.
All motion is relative. The question "is this object moving?" is in fact meaningless unless we specify "moving relative to what other object". Similarly, there is no such thin…g as "absolute rest": it's just as true to say that the road is moving at 50 km/h relative to your car as it is to say that your car is moving at 50 km/h relative to the road.

If you want to know what kind of energy then it is kinetic energy
motion is anything that moves. Therefore if anything is moving it is in motion
By using an Arrow (VECTOR) to represent its SPEED and DIRECTION. Where the Arrow points is its Direction of Motion, and its LENGTH (magnitude) is its SPEED.
That's the object's 'speed'.
