When is an object is consider to be in motion?
When the force acting on an object points at least partially in the direction of the motion the work being done is considered to be negative?
If the force moving an object points at least partially in the opposite direction of the object's motion what is the work considered to be?
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.

Inertia is the tendency of an object to resist a change in its motion.
the speed increase
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.
when the object is at rest
An object at rest has constant velocity of zero, thus still uniform motion.
Friction can slow an object in motion down. example, your car there is more than one force of friction acting on the car there is the friction between the tires and the …road, along with the friction caused by air against the actual car itself if you lift off the accelerator while driving on a flat slope, the car will start to gradually slow down The answer depends. If the object is on a smooth surface, then the object will be in motion for a longer period of time. If the object is on a rought surface, then the object will stop completely. Either way, the object will slow down or stop. It works to slow down
it was called inertia
force is directly proportional to acceleration, when a force is applied on an object it accelerates in the direction of force.... Force affects the motion by force moves the… motion. From Mamamean ^_^: Newtons 2nd law of motion states: An object in motion will stay in motion, and an object out of motion will stay out of motion, unless met with an unbalanced force.
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.
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.
When the force acting on an objects points at least partially in the blank direction of the motion the work done is considered to be what?
Positive work is work done in the direction of motion, while negative work is work done in the opposite direction from the motion. opposite
If the force moving an object points at least partially in the opposite direction of the object's motion the work is considered to be?
