The chef is lifting the plate up, causing a negative acceleration on the plate..]]> 2018-05-21 19:48:08 UTC https://padlet.com/bv128224/d8vqtdir65xa/wish/262492861 bv128224 https://padlet.com/bv128224/d8vqtdir65xa/wish/262493089 The ball was first at rest, but then the soccer player kicks it (unbalanced force) and causes the ball to be in motion. Then, friction from the ground would cause the ball to stop eventually. ]]> 2018-05-21 19:49:15 UTC https://padlet.com/bv128224/d8vqtdir65xa/wish/262493089 bv128224 https://padlet.com/bv128224/d8vqtdir65xa/wish/262493687 The glove is attached to a spring, The girl would launch out the glove (with negligible air resistance), and it would represent simple harmonic motion. As the glove extends outward, there will be an increasing force that acts against the direction of motion to bring the glove back to its equilibrium position, and vice versa for when the spring of the glove compresses.. ]]> 2018-05-21 19:52:05 UTC https://padlet.com/bv128224/d8vqtdir65xa/wish/262493687 bv128224 https://padlet.com/bv128224/d8vqtdir65xa/wish/262494330 The man is sliding on the ground, but the friction from the ground does negative work on the man, causing him to stop quickly.]]> 2018-05-21 19:54:43 UTC https://padlet.com/bv128224/d8vqtdir65xa/wish/262494330 bv128224 https://padlet.com/bv128224/d8vqtdir65xa/wish/262494547 Impulse means a change in momentum. Having the bat hit the baseball would cause it to change directions and velocity. The momentum would change. ]]> 2018-05-21 19:55:43 UTC https://padlet.com/bv128224/d8vqtdir65xa/wish/262494547 bv128224 https://padlet.com/bv128224/d8vqtdir65xa/wish/262494858 The groceries were in free fall after they broke out of the bag and before hitting the ground.
