A displacement vs. time graph of a body moving with uniform (constant) velocity will always be a line of which the slope will be the value of velocity. This is true because velocity is the derivative (or slope at any time t) of the displacement graph, and if the slope is always constant, then the displacement will change at a constant rate.
Velocity is a vector quantity, thus you must consider both magnitude and direction. The direction determines whether the value is positive or negative too
Direction and speed which is also velocity.
Motion that is always along the same straight line is referred to as rectilinear motion. This type of motion can be described using distance, displacement, velocity, and acceleration along a single axis.
Work is equal to Force * displacement * cos(angle between force and displacement). When there is uniform circular motion, the displacement is in the same direction as the velocity: along the tangent of the circle. The centripetal force always points towards the center of the circle. These two directions (vectors) are perpendicular to each other (90 degrees). Cos(90) = 0, so the work is 0.
if the field strength of induction is same at every point in both magnitude and direction is called uniform magnetic field. in uniform magnetic field the lines of force are straghit parallel and equidistant.
Displacement and distance are numerically equal if an object travels in a straight line. However, when indicating displacement, the direction should also always be indicated.
Yes. It always is when the motion is all in a straight line.
The ratio of an object's displacement to the interval during which the displacement occurred gives you the object's average velocity. It is calculated by dividing the displacement by the time interval. Average velocity is a vector quantity that indicates both speed and direction of the object's motion.
You cannot because a dispacement-time graph is concerned only with motion in a radial direction; any motion in a transverse direction is completely ignored. For example, an object circling the origin at a fixed distance, even with a variable speed, is always at the same distance from the origin. So the displacement-time graph will be a straight line whose height is the radial distance. A straight line in the distance-time graph is to be interpreted as no motion! Really?!The average velocity in the radial direction is the final displacement minus the starting [initial] displacement, all divided by the difference in time between the two points. The instantaneous velocity in the radial direction is the slope [gradient] of the graph at the point in question.
Uniform motion refers to an object moving in a straight line with a constant speed, where the object covers equal distances in equal intervals of time. In such motion, the object's velocity does not change, and there is no acceleration or deceleration involved.
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
