Learn where the centripetal acceleration formula comes from with a clear, step-by-step derivation. This video explains circular motion, velocity direction changes, and the physics behind the equation, ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

Can a human ever fall faster than terminal velocity? This video explores the physics of air resistance, acceleration, and real-world scenarios like skydiving to explain what terminal velocity really ...

Velocity is always TANGENT to the path. Acceleration, in general, has BOTH tangential and normal components. The normal component of acceleration always points INWARD to the path. The tangential ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

The questions in this quiz are suitable for GCSE physics students studying motion in a straight line, velocity and acceleration, distance-time graphs, velocity-time graphs and velocity, acceleration ...
