It demonstrates the measurements to take to calculate velocity and acceleration. Students could be asked to predict the effect of increasing mass and increasing force on acceleration of an object.

Do you feel acceleration in space if you aren't close to an object with enough gravity? It's a way tv shows [illustrate] motion but I feel like that isn't going to be accurate without gravity.

Measuring acceleration using a double mask When an object does not start at rest, you need to measure both the initial velocity and the final velocity to be able to calculate the acceleration.

Interstellar object Oumuamua has remained quite a mystery since it was discovered. A team of scientists has now found a rather simple explanation for its odd non-gravitational acceleration ...
