Motion Characteristics for Circular Motion
... constant speed - is one of many forms of circular motion. An object moving in uniform circular motion would cover the same linear distance in each second of time. When moving in a circle, an object traverses a distance around the perimeter of the circle. So if your car were to move in a circle with ...

... will have another factor of ω in it’s amplitude and jump to the answer vmax = Aω = 6π cm/s. The maximum speed occurs when the position is zero. Our particle starts at x = 0, so it has maximum speed at t = 0, T /2, T, 3T /2, . . .. We’re asked for the first occurence for t > 0, so t = T /2 = 1/2f = 0 ...

Compression of the spring: The mass keeps moving on the horizontal frictionless surface untill it hits the spring with spring constant k = 104 N/m and comes to rest after compressing the spring by a length x. Note that in the relaxed state the compression in the spring is zero. The goal of this s ...

... 10. A ball is released from rest above a horizontal surface. The graph shows the variation with time of its velocity. Areas X and Y are equal. This is because: A the ball’s acceleration is the same during its upward and downward motion. B the speed at which the ball leaves the surface after an impac ...
