WebThe components of a vector can be positive, negative, or zero, depending on whether the angle between the vector and the component-direction is between 0° 0 ° and 90° 90 ° or 90° 90 ° and 180° 180 °, or is equal to 90° 90 °. WebDec 9, 2024 · Explanation: Since the angle between the force and displacement is 180 degrees, the work done by the gravitational force on the body is negative. ... Hence for negative work done, angle between force and displacement is 1800. Advertisement. WebFor angle θ = 0°, the work done is positive, so it is not true. For angle θ = 45°, W = F.d/√2. In this case also, work done is positive, so it is not true. Work done at θ = 90°, W = 0. So, it is not true. Now, work done at θ = 180°, W = -F.d. For negative work, the angle between the force and displacement should be 180°. tshc otpr login

WebSorted by: 10. In the context of classical mechanics as you describe, negative work is performed by a force on an object roughly whenever the motion of the object is in the opposite direction as the force. This "opposition" is what causes the negative sign in the work. Such a negative work indicates that the force is tending to slow the object ... tshc otprWebNegative work is done when the displacement is in the opposite orientation of the force delivered. Example: The gravity on some kind of rocket moving vertically upwards was worked on. Zero work: Whenever force and displacement, are perpendicular to one another, or even when either force or displacement is zero. tshc otr
