Under what condition will the displacement and distance have the same magnitude ?
Q.1. Under what condition will the displacement and distance have the same magnitude ?
Ans. When the object has uniform motion.
Q.2. Can a body have constant speed and still be accelerating ?
Ans. Yes. When the body moves along a circular path with uniform speed, it possesses centripetal acceleration.
Q.3. A boy hits a football high up into the air. He runs and catches the football before it hits the ground. Which of the two, the boy or the football has had greater displacement?
Ans. Both have undergone the same displacement, although the distance travelled by the football is greater than the distance travelled by the boy.
Q.4. Under what conditions of motion, the distance covered by a body is equal to the magnitude of its displacement?
Ans. This happens, when the body moves along a straight line path, without reversing its direction of motion.
Q.5. What is the nature of the displacement-time graph of a body moving with constant velocity?
Ans. Straight line, passing through the origin.
Q.6. What is the slope of the displacement- time graph when the body has uniform motion?
Ans. The slope of the displacement-time graph gives the value of the uniform velocity.
Q.7. What is the nature of the displacement-time graph of a body moving with constant acceleration?
Ans. The graph is a parabola.
