Can the distance travelled by a particle be zero when displacement is not zero ?
Q.1. Can the distance travelled by a particle be zero when displacement is not zero ?
Ans. No.
Q.2. If the acceleration of a particle is constant in magnitude but not in direction, what type of path is followed by the particle?
Ans. The particle follows a circular path.
Q.3. How can you find the distance travelled by body in uniform motion from the velocity-time graph ?
Ans. The area under the velocity- time graph gives the distance travelled by the particle.
Q.4. If the displacement of a body is proportional to the square of the time elapsed, what type of motion does the body possess ?
Ans. The body has uniform acceleration.
Q.5. If the displacement of a body is proportional to the time elapsed, what type of motion does the body possess?
Ans. The body possesses uniform motion.
Q.6. When is an object in motion considered to be a point object?
Ans. The object in motion is considered to be a point object, if the distance it travels is very large as compared to the dimensions of the object.
Q.7. Can the speed of a body be negative?
Ans. No, because the speed of a body is the ratio of distance and time and distance travelled is never negative.
