In which of the following cases a force is used to change the direction of motion of the object?
Which of the following is not an effect of force ? (a) a force can change the speed of a moving object (b) a force can change the direction of a moving object (c) a force can change the composition of a moving object (d) a force can change the shape and size of an object
Observation 1: Try to stop a ball coming towards you,so as to save a boundary, by applying a force of some magnitude in the opposite direction of the motion of ball.
Observation 2: In this case apply the force of same magnitude but in same direction of the motion of the ball.
In observation 1 boy saves a boundary by applying a force opposite to the direction of motion but in observation 2, the change in direction of force cost the team 4 runs as the change in direction of force pushed the ball further to the boundary.
So, the change in effect of a force can be experienced by a change in it's direction as well as magnitude. The above statement is :-
Which of the following statement(s) about motion is/are true? Statement 1: Motion of an object is relative to the position of another object. Statement 2: Change in state of motion of an object is the result of an external force. Statement 3: Motion of an object is change of position of the object with respect to time.
