When a car is moving, it is possessing high kinetic energy, as it has a great mass and potential to go to great speeds.]]> 2017-05-18 14:04:06 UTC https://padlet.com/dp341659/42zfcxgq016k/wish/172586669 dp341659 https://padlet.com/dp341659/42zfcxgq016k/wish/172586783 The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. A stretched spring has high potential energy. When released, kinetic energy will be released. ]]> 2017-05-18 14:04:19 UTC https://padlet.com/dp341659/42zfcxgq016k/wish/172586783 dp341659 https://padlet.com/dp341659/42zfcxgq016k/wish/172586825 Centripetal acceleration is the rate of change of tangential velocity. Our moon moves in a circle so its direction changes continually; that means it has an acceleration because its velocity changes. This is an example of centripetal acceleration.

The pendulum of this clock is an example.]]> 2017-05-18 14:04:34 UTC https://padlet.com/dp341659/42zfcxgq016k/wish/172586864 dp341659 https://padlet.com/dp341659/42zfcxgq016k/wish/172586895 A free falling object is an object that is falling under the sole influence of gravity. When I drop this ball, the ball is traveling 9.8 m/s^2.]]> 2017-05-18 14:04:40 UTC https://padlet.com/dp341659/42zfcxgq016k/wish/172586895 dp341659 https://padlet.com/dp341659/42zfcxgq016k/wish/172586939 An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. These box of tissues will stay at rest unless an unbalanced force acts upon it. ]]> 2017-05-18 14:04:47 UTC https://padlet.com/dp341659/42zfcxgq016k/wish/172586939 dp341659 https://padlet.com/dp341659/42zfcxgq016k/wish/172586986 When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this fan has a positive acceleration. When the fan starts up from rest, the fan accelerates.]]> 2017-05-18 14:04:55 UTC https://padlet.com/dp341659/42zfcxgq016k/wish/172586986 dp341659 https://padlet.com/dp341659/42zfcxgq016k/wish/172587024  If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion, which is negative acceleration. When I roll this ball, the ball is demonstrating negative acceleration, because it is slowing down due to the frictional force from the opposing side of motion.

When I roll a car towards the wall, the wall acts as an impulse which results in the car stopping from collision with the wall. ]]> 2017-05-18 14:05:03 UTC https://padlet.com/dp341659/42zfcxgq016k/wish/172587062 dp341659 https://padlet.com/dp341659/42zfcxgq016k/wish/172587080 Work is displacement of an object due to force. First, the object must move over some distance in order for work to be done. Second, the force and the distance of movement must be in the same direction. And finally, the force must be constant. As I am lifting this book upwards, the book is moving some distance and in the same direction as I am lifting it. Thus, work is being done. ]]> 2017-05-18 14:05:06 UTC https://padlet.com/dp341659/42zfcxgq016k/wish/172587080
