Centripetal force - Study guides, Revision notes & Summaries

Question 1 Correct 5.00 points out of 5.00 A 0.200 kg dart is fired horizontally at a speed of 2.75 m / s when it hits a 0.700 kg block ofwood suspended by a string. The nose of the dart sticks into 0.00210 m the wood. Together the dart and block swing upwards from a height of 0.0500 m above a table to 0.128 m above the table. Which of the following is the average force the dart applies to the block during impact? Select one: a. 32.4 N b. 15.1 N c. 1.36 N d. 0.872 N Straighterl...

The tide-generating force is inversely proportional to the cube of the distance. - True There is no horizontal tide-generating force on Earth at points directly below and opposite the Moon. - True The barycenter follows: - a smooth orbit around the Sun. The difference between centripetal forces and gravitational forces is called the: - resultant force. t A If the resultant force has a significant horizontal component (tangential to Earth's surface), it produces tidal bulges on Earth, cre...

Inspecting Vehicles best practices Ans - frequent inspections reduce chances of mech or perform fails - if a defect found during inspection may impact performance or safety repair vehicle before using Driving triangle Ans 1.Driver (biggest) le ay Kinetic energy Ans The energy an object possesses by virtue of being motion Momentum Ans The combined mass and velocity of an object. The object tends to remain in motion until acted on by outside force Rolling friction Ans Occurs when a...

Emergency Vehicle Operations (EVOC) Questions and Answers Already Passed Three (3) main factors that directly impact basic motor vehicle operations are: -Vehicle -Driver -Roadway Laws of Physics: 1) Kinetic energy Energy an object possesses by being in motion. 2) Momentum Is the combined mass and velocity of an object. An object in motion tends to remain in motion until acted upon by an outside force. 3) Friction Is resistance between two objects rubbing against each other. * Rolling Frictio...

Newtons first law of motion correct answers (law of inertia) An object at rest will stay at rest unless a force acts upon it. An object in motion will not change it's velocity unless a force acts upon it. Newtons second law of motion correct answers Acceleration is produced when a force acts on a mass. The greater the mass the greater the amount of force needed. (F=M*A) Newtons third law of motion correct answers For every action there is an equal and opposite reaction. Newtons law of ...
