Work done by a force of i kg m s2 which moves an object a distance of 1 m in a specified direction is termed as (a)a joule (b) 1 pascal (c) 1 watt (d)1 ohm 10. a car moves 3 times as fast as another identical car. compared to the slower car, the faster car has: (a) 3 times the k. e. (b) 6 times the k. e (e) 9 times the k. e.(d)27 times the k. e 11.a toy train rolls along a track with considerable momen- tum. if it rolls at the same speed but has twice as much mass, its momentum is b) dogbled v (a) zero (d) unchanged x (c) quadrupled 12. if you find that twice as much work is needed to perform a task but it takes twice as much time, the amount of power required is (b) four times as much (a) twice as much (d) unchanged (e) sixteen times as much 13.if an object is raised twice as high, its potential energy will be: (a) half as much (b) four times as much (d) unchanged (e) twice as much 14. a clerk lifts a 5 kg container a vertical distance of 1 m. how much is the potential energy stored in the container at the top? 5 x1-5 (b) 5jv (a) 0.5 j (e) 50 j (d) 500 j 15. a clerk rolls a 5 kg container up a 2 meter- long ramp to al meter elevation. how much is the potential energy stored in the container at the top of the ramp? (a) 0.5 j (b) 5 j (c) 50 j (d) 500 j 16. a clerk can lift containers a vertical distance of 1 meter or can roll them up a 2 meter long ramp to the same elevation. with the ramp, the applied force required is about: (a) half as much (b) four times as much (e) twice as much (d) the same
