An assistant for a football team carries a 26.0 kg cooler of water from the top row of the stadium, which is a distance h = 20.5 m above the field level, down to the bench area on the field. The speed of the cooler is constant throughout the trip. Calculate the work done by the assistant on the cooler of water Number Calculate the work done by the force of gravity on the cooler of water. Number

How are calculation for velocity and speed different

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

The seven sisters, seven stars located more than 400 light-years away in the taurus constellation can be seen here with venus and another constellation, orion. the seven stars stay grouped together but seem to move, like the planet venus. why do stars seem to move like planets in the night sky?
