In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

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 ...

According to the study, interstellar object 3I/ATLAS showcased its first sign of a non-gravitational acceleration at perihelion, or the point of closest approach to the Sun. The non-gravitational ...
