work = force * distance and force = mass * acceleration and
acceleration = change in velosity/change in time
so work = mass * acceleration * distance ,
as a result work = mass * change in velosity/change in time * distance,
hence the velocity of the object affected by :
1.mass of the object.
2. gravitational acceleration which reduces the speed of the object when go up and increases the speed of the object when it come down..
3. look at the rules etc........thx..............with best regards
No, they are not the same! Velocity involves the speed and the direction of the moving object...
An object which is not changing in it's position in space. In simply it is at rest
... continue to do that, until a force is exerted on it.
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
Acceleration = Final velocity - Initial velocity / time
None, velocity is the speed at which something moves, they are the same thing
If the group of forces on an object is unbalanced, then the object can't have constant velocity. Its speed or the direction of its motion must change.
Velocity tells you what speed a moving object travels at and in what direction.
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
acceleration is the increase of speed in a moving object. velocity is the speed and direction of a moving object.
The factors affecting kinetic energy are mass and velocity.
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
Generally, the velocity as it is squared, but I suppose if you had some titanic mass moving at a very slow velocity then it could be the mass.
Momentum
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
