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 ...

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 ...

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 ...

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 ...
