Definition: It states that an object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an unbalanced force. Examples: It includes why a golf ball (at rest on a tee) will stay at rest unless acted upon the unbalanced force of a club, a...
Perhaps the most fundamental aspect of physics is the relationship between an applied force and the motion of an object. Because forces and motion permeate so many levels of physics, they allow a plethora of hands-on activities for students. Students just introduced to the material can benefit f...
force,commonly, a “push” or “pull,” more properly defined in physics as a quantity that changes the motion, size, or shape of a body. Force is avectorquantity, having both magnitude and direction. The magnitude of a force is measured in units such as the pound,dyne, andnewton, dep...
Describing Motion Essential Question: Are distance and time important when describing motion? Motion Definition Speed A change in position over time Measures the rate of motion (how fast something is going) Speed = distance (miles, km, m, in, cm, Motion Physical Science Chapter 11. Are You M...
(Pushing a pebble clearly takes less force than pushing a boulder, and pushing a boulder quickly obviously takes more force than pushing it slowly.) What is now known as Newton's second law of motion sets down this relationship quantitatively: Force equals mass times acceleration, or F = ma...
