Answer the following questions in detail: 1. Explain the various effects of force. State one example of each force.
Answers
Answer:
A Force Can Set Any Stationary Object in Motion - When force is applied to a stationary object, the object tends to move in the direction in which force is applied. For example, when a force is applied to a stationary tennis ball, it will make the ball continue its motion in the direction of the applied force.
A Force Can Either Stop or Slow Down the Moving Object - Force needs to be applied on a moving object either to stop it or to slow down the object. For example, the motion of the moving ball can be stopped by applying external force.
Force is Applied to Change the Direction of Moving Body/Object - The direction of any moving object can be changed by applying the external force on that particular object. For example, the direction of the moving football can be changed by applying force at an angle.
The Shape of an Object Can Also be Changed by the Application of Force - Consider a rod that is circular in shape, by hammering the rod which is applying an external force, the shape of the rod can be turned into a flat sheet.
Force Can be Used to Change the Speed of the Moving Object - When we keep on pedaling the pedal of the bicycle, the speed of the bicycle increases. And when we apply the brake, the speed of the bicycle decreases.
