Since my retinas diverge light coming into my eyes too much, the lenses converge the light so that the image is clear.

Although the ball is considered to be a projectile, it is also considered a falling object. In other words, if the same ball was dropped straight down from the same height, it would have reached the ground at the same time as the ball that was thrown with an initial outward velocity.]]> 2017-09-03 21:29:32 UTC https://padlet.com/bluessam000/realworldphysics/wish/184433849 bluessam000 https://padlet.com/bluessam000/realworldphysics/wish/184434004 2017-09-03 21:32:10 UTC https://padlet.com/bluessam000/realworldphysics/wish/184434004 bluessam000 https://padlet.com/bluessam000/realworldphysics/wish/184434036 When you pull back on the air gun, the tension and elastic potential energy in the elastic strings increases greatly. When the gun is released, the tension in the strings is released and converted into a combination of kinetic and sound energy.]]> 2017-09-03 21:32:43 UTC https://padlet.com/bluessam000/realworldphysics/wish/184434036 bluessam000 https://padlet.com/bluessam000/realworldphysics/wish/184434283 When the tension in the strings are released, some of the potential energy is converted into sound energy. This energy is emitted in waves. The combination of kinetic and sound energy will keep the energy of the system constant. ]]> 2017-09-03 21:37:00 UTC https://padlet.com/bluessam000/realworldphysics/wish/184434283 bluessam000 https://padlet.com/bluessam000/realworldphysics/wish/184434516 The charger swinging back and forth acts as a pendulum. The period of the pendulum is dependent on the length of the pendulum and the force of gravity on the object. The period is not dependent on the mass of the object.]]> 2017-09-03 21:41:22 UTC https://padlet.com/bluessam000/realworldphysics/wish/184434516 bluessam000 https://padlet.com/bluessam000/realworldphysics/wish/184434723 The open door is an example of torque. The point of rotation of the door is the hinge on the far left side. The applied force to the door to open it is applied to the knob, which is farther away from the hinge. Since the knob is farther away, the torque applied on the door is maximized, thus making it easier to open the door.]]> 2017-09-03 21:44:30 UTC https://padlet.com/bluessam000/realworldphysics/wish/184434723 bluessam000 https://padlet.com/bluessam000/realworldphysics/wish/184434931 The flower at the bottom of the tennis racket is called a dampener. Dampeners are meant to decrease the amplitude of the waves that result from hitting the tennis ball. This allows for the player to have more power and control on their shots. ]]> 2017-09-03 21:48:03 UTC https://padlet.com/bluessam000/realworldphysics/wish/184434931 bluessam000 https://padlet.com/bluessam000/realworldphysics/wish/184435600 The hands on clocks are examples of circular motion. The second hand completes a revolution in 60 seconds, the minute hand completes a revolution in 60 minutes, and the hour hand completes a revolution in 12 hours. Each hand has a unique angular speed and momentum based on their length and circumference of the clock itself.]]> 2017-09-03 21:59:04 UTC https://padlet.com/bluessam000/realworldphysics/wish/184435600 bluessam000 https://padlet.com/bluessam000/realworldphysics/wish/184436469 Without any outside forces acting on it, the cooler does not move because of friction. When the cooler is pushed, the force of friction acts in the direction opposite that of the motion. The coefficient of friction of the surface as well as the normal force applied by the surface onto the object determines how much frictional force is present. A greater coefficient means that the surface is rougher while a decreased coefficient of friction means that the surface is smoother. ]]> 2017-09-03 22:08:09 UTC https://padlet.com/bluessam000/realworldphysics/wish/184436469
