1. Motion (Speed - Distance)A car is moving along a straight road at a constant speed of 20m/s. What distance will it cover in 10 s?[list][*][/*][/list]

[list][*]200 m[/*][/list] [list][*]30m[/*][/list] [list][*] 2 m[/*][/list]

2. Forces (Newton's Laws)When you push a heavy box across the floor and it begins to accelerate, this means that the net (resultant) force acting on it is:

[list][*] Less than the friction force[/*][/list] [list][*] Not equal to zero (constant or variable) [/*][/list] [list][*] Equal to zero[/*][/list]

3. Gravity (Weight and Mass)If you take an object from Earth to the Moon, where gravity is about 6 times weaker, what will happen to its mass and its weight?

[list][*][b]c)[/b] Its mass will remain the same, but its weight will decrease by 6 times. [/*][/list] [list][*] Its mass will decrease, but its weight will stay the same.[/*][/list] [list][*] Both its mass and its weight will decrease by 6 times[/*][/list]
