Force that produces an acceleration of 1 ms⁻² in a body of mass of 1 kg is called

A horizontal force of 100 N pulls two masses 5 kg and 10 kg tied to each other by a light string. What is the tension in the string if the force is applied on 10 kg mass?

A man weighing 100 kgf carries a load of 10 kgf on his head. He jumps from tower with that load. What will be the weight of load experienced by the man.

For a body to be able to loop a vertical circle of radius R, the minimum velocity required at its lowest point is:

A block of 5 kg mass rests on a horizontal floor. The action of the block on the floor is

A lift is moving down with the acceleration 3 m/s². A ball is released 1.7 m above the the lift floor. How long will it take to hit the lift floor.

A body of mass 2 kg is hung on a spring balance mounted vertically in a lift. If the lift moves up with an acceleration equal to the acceleration due to gravity, the reading on the spring balance will be

A block of mass m is pulled by applying a force F at an angle θ with the horizontal surface. Its acceleration will be given by

Consider two blocks of masses m1 and m2 placed in contact with each other on a friction less horizontal surface. Let a force F be applied on block of mass m1, then the value of contact force between the blocks is

The couple and the other two force systems in free body diagrams can be easily simplified.
