Work W done by a constant force F that produces a displacement L in the direction
of the force is :
W = F∙L
for the case stated: W = 100N∙20m = 2 000J (joules)
The mass of the object is not involved in the calculation.
In the direction of
The direction of their motion changes randomly.
This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.
The speed increases. The object accellerates positively in the direction of motion.
A body moving in a circular path has no fixed direction. Its direction keeps on changing with every step of its motion.
In the direction of
acceleration in a direction that is not parallel to the direction you are moving
acceleration in a direction that is not parallel to the direction you are moving
is a moving motion in diffrent direction
When a moving object is pushed in the direction of its motion the speed of the object increases
When a moving object is pushed in the direction of its motion the speed of the object increases
Horizontal force is motion parallel to the ground.
The direction of their motion changes randomly.
it will be in the same direction in which it is moving. If it is not moving it will remain at rest
newtons first law: she will not move unless an outside force acts upon her, like her feet moving or her partner moving her!
This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.
If you apply force to an object, you accelerate it. If you apply the force in the direction that the object is moving, you speed it up. If you apply it in the opposite direction, you slow it down. If you apply the force in another direction than the object is moving in you will change the direction of the objects motion. The amount of acceleration is given by a = F/m where a is acceleration, F is force and m is the mass of the object.
