PhysicsJEE/NEETKinematics: the misconceptions that cost marks
5 wrong ideas students commonly carry in Kinematics. Each page has a one-question check and a careful explanation of what's actually true.
- Why is acceleration not zero when velocity is zero?Myth: If velocity is zero at an instant, acceleration must be zero too.
- Is average speed the same as the magnitude of average velocity?Myth: Average speed is always equal to the magnitude of average velocity.
- Does a heavier object fall faster than a lighter one?Myth: In free fall (no air), a heavier object falls faster.
- Does negative acceleration always mean slowing down?Myth: Negative acceleration always means the object is slowing down.
- Is velocity zero at the top of a projectile's path?Myth: At the top of a projectile's path its velocity is zero.
