As an example of constant speed, though acceleration (force) is present. Differences between centrifugal and centripetal force.
A uniform metre rule of weight 10gf is pivoted at its 0 mark.
How can it be made horizontal by applying a least force ?
A uniform metre rule of mass 100g is balanced on a fulcrum at mark 40cm by suspending an unknown mass m at the mark 20cm.
To which side the rule will tilt if the mass m is moved to the mark 10cm ?
State True or False
In a uniform circular motion, the speed continuously changes because of the direction of motion changes.
Give scientific reason for the following:
A man runs in the direction of train while getting down from a moving train.
