Major steps for analyzing forces in uniform circular motion: Let consider one axis along the radius of circle (i.e. in direction of acceleration) and other axis perpendicular to the radius. Resolution all the forces into horizontal and vertical components.
Net force along perpendicular axis=zero
Total force along radial axis (towards centre) =mv2/r=mω2r
when do we use projected area instead of actual area and why
IF a football player kicks a football so that it spends 3.0 seconds in the air and travels 50m, then find the velocity and angle of the kick.
Hiker stands at the bottom of steep hill. The hiker may follow a straight line path to the top of the hill, a distance of 300 feet, or she may follow a zig-zag path to the top of
Sliding versus Static Friction: Friction force is the force exert by a surface as an object moves crosswise it or makes an effort to move across it. Two types of friction force
How to find the acceleration of a body in a non inertial frame on the action of friction? Solution) Use the concept of pseudo force. Multiply the mass of the body of which you
