Answer:

Question 1. The phenomenon of motion was placed on a sound scientific footing by two scientists. Write their names.

Question 2. Are rest and motion absolute or relative terms?

Question 3. Suppose a ball is thrown vertically upwards from a position P above the ground. It rises to the highest point Q and returns to the same point P. What is the net displacement and distance travelled by the ball?

Question 4. Which speed is greater: 30 m/s or 30 km/h?

Question 5. What do you mean by 2 m/s2?

Question 6. Can uniform linear motion be accelerated?

Question 11. What is the simplest type of motion?

Question 12. What indicates the motion of the earth?

Question 13. If the displacement of a body is zero, is it necessary that the distance coyered by it is also zero?

Question 14. Can the displacement be greater than the distance travelled by an object?

Question 15. When do the distance and displacement of a moving object have the same magnitude?

Movement of any object from one position to another position with respect to the observer is called as Motion. Motion Along a Straight Line: When an object moves along a straight line, the motion of the object is called rectilinear motion. For example; motion of a car on highway.
