(a) differentiate between uniform linear and uniform circular motion.
(b) write any four examples of uniform circular motion.
(c) is uniform circular motion accelerated motion?
Answers
Uniform circular motion:1} When a body moves in circular path with uniform speed , it's motion is called uniform circular motion.2} SPEED is constant but direction of motion changes every point.3} Motion is said to be accelerated.
(b) An artificial satellite orbiting the Earth at a constant height, a fan's blades rotating around a hub, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field.
(c) Yes, uniform circular motion is an accelerated motion since in uniform circular motion only the speed is constant but it's velocity is not ( since it's direction changes at every point).
Hope it helps u.
Answer:
(a)Uniform Linear motion:
1} An object is said to move in uniform linear motion , if it travels in straight line and covers equal DISTANCE in equal time interval.
2} SPEED is constant and constant velocity.
3} No change in direction.
Uniform circular motion:
1} When a body moves in circular path with uniform speed , it's motion is called uniform circular motion.
2} SPEED is constant but direction of motion changes every point.
3} Motion is said to be accelerated.
(b) An artificial satellite orbiting the Earth at a constant height, a fan's blades rotating around a hub, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field.
