EDT Notes Direction + speed = velocity Change in velocity = acceleration Motion Change motion by how fast it is going. Change in velocity or speed. Change in direction results in an acceleration Forces- Historical Background 1. Aristotle- heavier objects fall faster and Objects moving horizontally require continuously applied force. 2. Galileo and Newton- all objects fall at the same rate and no force required for uniform horizontal motion. Force: A push or pull capable of changing an objects state of motion. No net force, no change in motion. Fundamental forces 1. gravitational - mass interactions - motions of planets, stars, galaxies 2. Electromagnetic - charge interactions - electicity and magnetism - atoms and molecules, chemisty 3. Weak force - Involved in certain nuclear reations 4. Strong force - holds nuclei together Blanaced and Unbalanced forces Natural motion in free space = constant velocity
