WebNov 26, 2015 · Because the axles on a train cause more resistance than the wheels, engineers consider the axle resistance to be part of the rolling resistance. Because axles tend to use fluid lubrication, axle resistance does depend upon speed. While there are exceptions, generally fluids cause friction that depends on speed, while solids do not. WebVelocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a …

WebAcceleration equals the change in velocity divided by time. Which statement best describes acceleration? Acceleration is the rate of change of velocity of an object. WebJul 20, 2024 · Recall that the direction of the velocity is always tangent to the circle. Therefore the direction of the velocity is constantly changing because the object is moving in a circle, as can be seen in Figure 6.4. Because the velocity changes direction, the object has a nonzero acceleration. Figure 6.5 Change in velocity vector.

WebJan 24, 2024 · Speed can be equal to or more than velocity. Velocity can be different with the same speed. Speed is the distance covered in time. ...
