Motion is accelerated
Standard7.3.17: Investigate that an unbalanced force, acting on an object, changes its speed or path of
motion or both, and know that if the force always acts toward the same center as the object moves, the
objects path may curve into an orbit around the

What is physics ?
The branch of science concerned with the
nature and properties of matter and
energy. The subject matter of physics
includes mechanics, heat, light and other
radiation, sound, electricity, magnetism,
a disturbance that transfers energy
Carries energy from one place to another
Classified by what they move through
1. Mechanical Waves
the energy is transferred by vibrations of
medium (medium = matter)
ex/ ocean waves move through water
What is Light?
Light is a wave, or rather acts like a wave.
How do we know?
