Immunity Challenge Chp 5

3. quantity required to accelerate 1 kilogram of mass
5. Weight of a bowling ball on Earth is different to weight measured on the moon, because the mass of the ball depends on the force acting on the ball, according to Newton's second law (m = F/g).
8. another word for center-seeking or radially inward
10. A cat of mass 5kg jumps on a dining table of mass 30kg. As the cat walks around on the table, is the average force that the table applies to the cat less , equal or more than 50N? (g = 9.8 m/s^2)
11. A quantity that can be measured while in a moving GauTrain and while stationary on the roof top, and still remain the same?

1. weight measured inside an elevator cab moving up at constant speed, will be equal to weight measured when the elevator stops on the 12th floor?
2. what is the total effect of all forces acting on the body, if that body is moving at constant velocity?
3. While pushing a trolley with mass m and acceleration a, a fly seats on your shoulder increasing your total mass, the acceleration of the trolley will change due to this.
4. When a person walks on the floor? which direction is the force applied by the person to move forward?
6. A driver pushes a car downhill and the car accelerates, after 5 seconds, the driver stops pushing the car, but the car continues to accelerate downhill. Which Newton's Law explains this scenario (1st, 2nd or 3rd)?
7. Mass measured inside an elevator cab moving up at constant speed, will be equal to mass measured when the elevator stops on the 12th floor?
9. A painting is hung by a wire on the nail on the wall, how many forces are acting on the nail?
