Physical Science Motions and forces The motion of an object can be described by its position, direction of motion, and speed. The motion can be represented on a graph. An object that is not being subjected to a force will continue to move at a constant speed in a straight line. If more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude. Transfer of energy Energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, sound.
Energy is transferred in many ways.
