When you hold a book, you exert a force that balances the force of gravity. When you let go of the book, gravity becomes an unbalanced force and the book falls. Free Fall When the only force acting on an object is gravity, the object is said to be in free fall.

WebAnswer Key To Phet Gravity Force Limited Pre-Publication Version, Physics - Dec 28 2024 The Cyclopaedia; Or, an Universal Dictionary of Arts, Sciences, and Literature - Nov 02 2024 Body Physics - May 09 2024 "Body Physics was designed to meet the objectives of a one-term high school or freshman level course in WebThe centripetal force points toward the center of the circle. That's why it's called centripetal. Gravity IS the centripetal force at the top of the hill. Gravity pulls down, normal force pushes up. The normal force is less than the gravitational force because the hill is curving downward away from the bike, and the bike is accelerating downward. WebGravitational force F_g F g is always attractive, and it depends only on the masses involved and the distance between them.
