Positive work is work done in the direction of motion, while negative work is work done in the opposite direction from the motion.
opposite

A force acting on an object does no work if?
the force is not in the direction of the objects motion.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Adding a force acting in one direction to a force acting in another direction is the same as anewton?
yes becase itsdhbsdvsahdvhsjshjshj
What forces are acting on all objects?
dvv
True or false if you know an objects mass and acceleration you can determine the net force being exerted on the object?
False. You will know nothing at all about any force acting perpendicular to the direction of motion.
What direction do objects moves when a force like push is applied?
It moves in the direction of the force acting on it.
A force acting on an object does no work if?
the force is not in the direction of the objects motion.
A net force acting on an object changes the objects what?
Direction or shape
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
What are the forces that result in no change in an objects. Motion?
Forces that are equal in magnitude, opposite in direction and acting on the same object will not create a change in said objects motion.
What acts against the direction of th objects motion?
Any force acting in the direction opposite to motion, such as Friction, wind resistance, or swimming up stream
How can you find the net forceif two objects are acting in opposite directions?
You subtract the smaller force from the larger force and use the direction of the larger force.
Can equal forces in opposite direction change an objects motion?
If the force is acting in the opposite direction to the movement, the object will slow down and then accelerate in the direction of the force. Negative for
What are the force acting on a fallen object what direction are these forces?
Assuming you mean "falling": the main forces are gravity (downward), and friction (in the direction opposite to the object's movement - for example, if the objects falls straight down, that would be upward).
Objects that do not accelerate?
All objects accelerate if the forces acting on them are not balanced.
Why do objects accelerate on ramps?
Objects will accelerate if there is a net force acting on them.
Adding a force acting in one direction to a force acting in the opposite direction is the same as adding what?
A negative force. Since the force added in the opposite direction works against the original force, you would subtract the added force from the original force. Since subtracting a positive is the same thing as adding a negative, this force would be considered negative to the positive direction.
