... • If I lift an object, I do work (F x d), and this work is stored as PE. The work done when I lift a mass m up a distance h is, W = F d = (mg) h = mgh • The PE that an object gets when it is lifted by an amount h is called Gravitational Potential Energy ...

... not talking about a new kind of force, but a new kind of situation in which the same old forces such as, the gravitational force, frictional force, normal force, the tension in a string, or a combination thereof constrain the object to follow a curved path. The centripetal force does NO work on an o ...

... Projectile Path Principles The greater the object’s horizontal motion (or speed), the wider the arc of its curved path. If thrown from the same height, both projectiles will land at the same time even if their horizontal speeds are different. See Figures 14.1 and 14.3 on page 263. ...

... The first law states that if the net force (the vector sum of all forces acting on an object) is zero, then the velocity of the object is constant. Velocity is a vector quantity which expresses both the object's speed and the direction of its motion; therefore, the statement that the object's veloci ...
