Reply to the student's statement, "I know there is a centrifugal force acting on me when I move in circular motion inmy car because I can feel the force pushing me against the side of the car''.

Statement - I: Work done in moving a body in non-uniform circular motion is zero. Statement - II: The centripetal force always acts along the radius of the circle

A block of mass m sits at rest on a frictionless table in a rail car that is moving with speed v_(c) along a straight horizontal track (fig.) A person riding in the car pushes on the block with a net horizontal force F for a time t in the direction of the car's motion. How much did K.E of the block change according to the person in the car ?

A block of mass m sits at rest on a frictionless table in a rail car that is moving with speed v_(c) along a straight horizontal track (fig.) A person riding in the car pushes on the block with a net horizontal force F for a time t in the direction of the car's motion. What is the final speed of the block according to a person in the car ?

A block of mass m sits at rest on a frictionless table in a rail car that is moving with speed v_(c) along a straight horizontal track (fig.) A person riding in the car pushes on the block with a net horizontal force F for a time t in the direction of the car's motion. In terms of F,m & t , how far did the the force displace the object according to the person in car ?

A car is moving along the circle x^(2)+y^(2)=a^(2) in the anti-clockwise direction with a constant speed. The x-y plane is a rough horizontal stationary surface. When the car is at the point ( a cos theta, a sin theta ), the unit vector in the direction of the friction force acting on the car is

Select the correct statement from the following. I. Positive force means repulsive force. II. Negative force means attractive force. III. When rate of change of force with distance is negative, it represents attractive force.

Three point masses A,B,C each of mass m are moving on the same circular path and are always equidistant from each other. The radius of circular is R and the speed of each mass is same and equal to V. The only force acting on each mass is the graviational force because of the other two masses. Choose the correct statement
