How does an inclined plane make work easier How does an inclined plane make work easier? How does it change the force that is applied to the inclined plane?

Key Objectives Students will be able to : Identify the forces acting on an object on an inclined plane. Resolve the force of gravity in to two components; along and perpendicular to the plane. Construct a free body diagram and apply Newton’s second law to determine the acceleration of the object

Steepest streets

Real World Application: Car Parked on a Hill and co efficient of friction

Example

Sample Problems: 1. A Block with mass 2.5 Kg sits on a frictionless ramp with an angle of inclination of 35˚ .How fast does the block accelerate down the ramp? A rope pulls a 63 kg water skier up a 14.0° incline with a tension of 512 N. The coefficient of the kinetic frictional force between the skier and the ramp is 0.27. Find the magnitude and direction of the skier’s acceleration. 100 Kg mass sliding on a frictional surface at a constant speed of 0.2 m/s. Find all the unknown .
