In a simulation on earth,an astronaut in his space suit climbs up a vertical ladder.On the moon,the same astronaut makes the same climb.In which case does the gravitational potential energy of the astronaut change by a greater amount?
Hello, i need help. This is Work-Energy Theorum A car moving at 50km/hr skids 15m with locked brakes. How far will the car skid (with locked brakes if the car moves at 100km/hr assume that the mass of the car is 500kg
You have a choice,you may get hit head-on by either an adult moving slowly on a bicycle or by a child that is moving twice as fast on a bicycle.The mass of the child is-one-half that of the adult on the bicycle.Which collision do you prefer ?
When you are driving a golf ball,a good follow-through helps to increase the distance of the drive. A good follow-through means that the club head is kept incontact with the ball as long as possible.Why does this technique allow you to hit the ball farther ?
