A journey describes the motion of an object over time. A journey can be represented using a distance-time graph. The graph will show when an object is moving and when it is stationary. The graph can ...

Swimmer Eric Shanteau placed third in the 200-meter breaststroke at the U.S. Olympic trials with a time of 2:10.05. This gives him an average speed of 1.538 m/s. Of course, this wasn’t his speed the ...

The questions in this quiz are suitable for GCSE maths students studying real-life graphs, distance-time and displacement-time graphs, speed-time and velocity-time graphs, instantaneous rates of ...

In my recent post about calculating the speed of light, I mentioned Ole Roemer's calculation in 1676. The basic idea uses the orbit of one of Jupiter's moons. The orbital period is constant, but there ...

Difference between Speed and Velocity: Speed and velocity are the most basic concepts from Physics. They form the part of your Physics textbook right from early classes when Physics is introduced as a ...
