Question

Which situation shows a non-contact force changing the speed of an object?

Answer 1

A situation that demonstrates a non-contact force changing the speed of an object is the effect of gravity on a falling apple. When an apple falls from a tree, it is not in contact with any surface, but gravitational force pulls it towards the Earth, causing it to accelerate and change its speed as it falls. Another example could be the force exerted by a magnetic field on a magnetically susceptible object, which can also change the speed of the object without any physical contact.
