Orodruin said:What is the difference between velocity and speed?
Also, speed and velocity are measured in m/s. The unit m/s^2 is used for acceleration.
MPZ said:velocity is a vector (with direction) while speed is a scalar , also i will fix the unit now
average velocity using v = wr , average speed = (v at y + v at x)/2 ?Orodruin said:So how would you compute the average speed and the average velocity, respectively?
No, neither of the above are correct for this problem. You need to take a minute to look up the definitions of average speed and average velocity. The Hyperphysics website page for average velocity is apropos. Pay particular attention to the section, "Average Velocity, General".MPZ said:average velocity using v = wr , average speed = (v at y + v at x)/2 ?
Circular motion refers to the movement of an object along a circular path, where the object maintains a constant distance from a fixed point and its direction changes continuously.
Speed is a measure of how fast an object is moving, while velocity is a measure of the rate and direction of an object's motion. In circular motion, an object's speed may remain constant, but its velocity is constantly changing as the direction of motion changes.
The radius of the circular path is directly related to the speed of the car. The smaller the radius, the greater the speed of the car needs to be in order to maintain the circular motion. This is because a smaller radius means the car must complete the circular path in a shorter distance, requiring a higher speed.
Centripetal force is the force that keeps an object moving in a circular path. In circular motion, the centripetal force is directed towards the center of the circle and is necessary to counterbalance the inertia of the object, which would otherwise cause it to move in a straight line.
Yes, in circular motion, an object can have a constant speed but changing velocity. This is because velocity takes into account the direction of motion, which is constantly changing in circular motion, even if the speed remains constant.
