State whether the following statements are True or False.
A force is always required to change the speed of motion of an object.
True. Any change in the speed of an object requires the action of a force.
Due to friction, the speed of the ball rolling on a flat ground increases.
False. Friction acts in a direction opposite to the motion, causing the ball to slow down and eventually stop.
There is no force between two charged objects placed at a small distance apart.
False. Electrostatic force acts between charged objects even when they are not in contact with each other.
Explanation
(i) As stated in the chapter, force can change the speed of an object if it is moving, and none of these changes take place without the action of force. (ii) The chapter explains that friction always acts in a direction opposite to the direction in which the object is moving, which causes objects to slow down. (iii) The chapter describes electrostatic force as a non-contact force that acts between charged bodies even at a distance.
