Objects in motion exhibit changes in position over time, which we can observe directly or infer through indirect evidence.

Motion can be inferred through indirect evidence, such as observing the movement of surrounding objects or changes in their positions.

Nerves are formed by bundles of nerve fibers (axons) bound together by connective tissue, allowing for the transmission of nerve impulses throughout the body.

Nerve impulses stimulate muscles to contract, allowing for coordinated movement in response to stimuli.

A nerve impulse is the electrical signal that travels along the axon of a neuron, allowing for rapid communication within the nervous system.
