Using the Law of Universal Gravitation
... The Gravitational Field 20. What type of force is gravity? Gravity is a field force. Gravity acts over a distance. It acts between objects that are not touching or that are not close together, unlike other forces that are contact forces. For example, friction. In the 19th century, Michael Faraday de ...

... A helicopter has a mass of 1000 kg. The rotation of the rotor blades can produce a maximum upward force of 15000 N. (a) What upward force must be produced by the rotation of the rotor blades to keep the uploaded helicopter at a constant height? (b) What is the maximum upward acceleration of the heli ...

... Answer: The maximum height reached by B is less than that reached by A. For A, all the kinetic energy becomes potential energy at h. Since the ramp is frictionless for B, all of the rotational K stays rotational, and only the translational kinetic energy becomes potential energy at its maximum ...

PHYSICS 2325 EXAM 2 REVIEW
... 79. A thin plate of negligible mass is attached to the end of spring A, which has k 1380 N m . The end with the plate is pressed against an identical spring B fastened to a wall until the force exerted on the end of A is 225 N. By how much has spring B been compressed from its unstretched length? ...
