because two objects of different masses do fall at the same rate. “Galileo’s measurements indicated that each body increased speed at the same rate‚ no matter its weight. This book is consisted of a lot of theoretical physics‚ which pretty much means is a lot of theories about physics whether it is right or wrong. Stephen Hawking gives a miniscule overview about how the current information was developed. From the universe‚ elementary particles‚ black holes‚ and the beginnings of the universe also what

Kinematics is motion. We are in a world full of motion. You jump up‚ and there is a counteracting force that will move you down. Drop a ball‚ and the ball will fall to the ground. Push on a shopping cart‚ and the cart moves forward. These are all examples of motion‚ but there is a lot more to it than just being at rest or being in motion. One example of kinematics in the real world is in roller coasters‚ a thrill-seeking pastime for many. First‚ to understand how a rollercoaster works‚ one must understand

In the first graph‚ the golf ball flew extremely higher than the wiffle ball when bounced off of the basketball. Therefore‚ it makes the forces unbalanced and allows the smaller balls to bounce higher from the motion of the larger balls. In the second graph‚ the golf ball also bounced significantly higher than the wiffle ball when bounced off of the volleyball. This means the more mass the top ball has‚ the more force energy is transferred into it. There was more energy transferred into the golf

Lab 5 Conservation of Momentum and Energy Abstract The physics laws governing conservation of momentum and mechanical energy were investigated by performing multiple experiments with differing conditions. Conservation laws state energy is to be conserved in systems with no net external forces. Two trials consisted of inelastic collisions and two trials consisted of elastic conditions. Photogate software helped decipher initial and final velocities in order

“The forces of interaction in an inelastic collision are non-conservative in nature” (Inelastic Collision).“Inelastic collisions are best known as one in which the kinetic energy is changed to some other form of energy in the collision” (Hyper Physics). These collisions can also been seen as the most ordinary types of collisions‚ for example a car crash. “If there are only two objects involved in the collision‚ then the momentum change of the individual objects are equal in magnitude and opposite

Investigation of the factors affecting the period of vibration of a weighted cantilever Introduction The aim of the experiment is to find out how the period T of vibration of a weighted cantilever depends on the vibrating length L. Hypothesis: Assume the relationship between the vibrating period T and vibrating length L is in accord with the equation: T=kLn‚ where k and n are both constant values. According to the hypothesis‚ the vibrating period T and vibrating length L is a linear relationship

1) Introduction This Lab is about conservation of momentum. It is to investigate the difference of momentum before and after collisions. Using the photo gates record the velocity of each cart‚ comparing momentum and kinetic energy to find the law. The experimental apparatus are two red carts in approximately same weight and a gold cart in lower weight than the red ones‚ a stable air track (blow a constant stream of air out through numerous tiny holes) with low friction and two photo gates. 2) Project
