How do forces and mass affect an objects motion?

Answers

Answer:

An object's change in motion in response to an external force is proportional to the mass of the item.

This alteration of motion, known as acceleration, is influenced by the mass of the item and the strength of the external force.

Hope this helps! :)

The greater the mass the greater the amount of force needed to accelerate the object. More force is required to move a heavier object than a lighter object.
