... 3. Understand how Newton’s Second Law, F = ma, applies to a body subject to forces such as gravity, the pull of strings, or contact forces, so they can: (a) Draw a well labeled diagram showing all real forces that act on the body. (b) Write down the vector equation that results from applying Newton’ ...

Friction, Circular Motion, Drag Forces 5
... Example 5-15: Banking angle. (a) For a car traveling with speed v around a curve of radius r, determine a formula for the angle at which a road should be banked so that no friction is required. (b) What is this angle for an expressway off-ramp curve of radius 50 m at a design speed of 50 km/h? ...

Inclined Planes and Friction
... (2) A force of 160. N parallel to an inclined plane is required to move a 200. N weight up the inclined plane with a constant velocity. Find the coefficient of sliding friction if the plane is inclined at 30.0 degrees. (3) A 15.0 m long plane is inclined at 30.0 degrees. If the coefficient of fricti ...

GRADE 10F: Physics 2
... Get pairs or small groups of students to use a forces board to measure forces acting on an object and draw the corresponding vector diagram. The diagram will probably show a (small) non-zero resultant force. Discuss the reasons for this (e.g. frictional forces, uncertainty in measurement of forces a ...
