Well, if you do that for a while, you could certainly raise a sweat, and you would say
that you've done a lot of work. But in the strict Physics definition of "work", none of
it has been done to the object you carried.
The strict definition is: Force acting through a distance.
Referring to the object you carry:
-- You don't move it vertically. You just hold it there against the force of gravity,
but your vertical force doesn't move it up or down. So no work is done vertically.
-- Horizontally, the speed is constant. No force is required to maintain a constant
speed, so no work is done horizontally either.
A body is said to move with uniform velocity if it has no acceleration. This implies that the body moves with a constant speed along a straight line path. This also means that the body moves with equal displacements in equal intervals of time, however small these time intervals may be.
I Dont know sombody help me on this an I'm on a quiz (:
Yes, an object can be moving and still be in equilibrium if the forces acting on it are balanced. This can occur when the object is moving at a constant velocity in a straight line with no net force acting on it.
I dont know, Help ME PLS You dougnuts
v=d/t Algebra can be used to isolate for the t value: Multiply by t: vt=d Then, divide by v: t=d/v Now, simply plug in the given values for the variables, and solve.
When you carry an object at a constant velocity, there is no net displacement in the direction of the force applied. Work is defined as force x distance x cos(theta), and since the displacement is zero in this case, the work done is also zero.
velocity. When an object changes direction, its velocity vector changes, even if the object's speed remains constant. This change in velocity can be caused by forces such as gravity or friction acting on the object.
why dont you draw the velocity of triangles?

simple... if you cant carry it.. then dont (:
i dont no why are you asking me i dont no why are you asking me i dont no why are you asking me
[object Object]
Momentum = mass x velocity. Using standard terminology, p = mv. Δp = m v - m0 v0 (Change in mass = mass x velocity - initial mass x initial velocity ) If your mass stays the same, this can be simplified to Δp = m ( v - v0 )
Weight is not constant because it depends on the gravitational pull acting on an object. Weight is a force that results from the mass of an object interacting with the gravity of the planet it is on. Therefore, if the gravitational pull changes, the weight of an object will also change.
No, even if a car is moving at a constant speed while rounding a corner, it is still undergoing centripetal acceleration towards the center of the curve. This acceleration is responsible for changing the direction of the car's velocity.
