Practice JEE Main lawsofmotion in the app →Newton's first law of motion is also known as the law ofA cricket ball of mass 150 g moving at (3i+4j) m/s is hit to -(3i+4j) m/s. The magnitude of momentum change isConservation of linear momentum in a collision follows directly fromA force F acts on a 2 kg body for 3 s, changing its speed from 2 m/s to 8 m/s along the line of F. The magnituThe maximum static friction force on a body is f = μN. Static friction is best described asA 10 kg block on a frictionless surface is pulled by 20 N horizontally and 20 N at 60° above horizontal. The hImpulse equalsA body in equilibrium under several forces hasA 0.5 kg ball hits a wall at 10 m/s and rebounds at 10 m/s. The impulse on the ball isNewton's second law in vector form isA lift accelerates upward at 2 m/s². The apparent weight of a 50 kg person (g=10) isTwo blocks of 2 kg and 3 kg connected by a string are pulled by 10 N on the 3 kg block (frictionless). The accThe SI unit of force, the newton, equalsA coin sitting on a bus seat slides forward when the bus brakes suddenly. This is best explained by:A batsman strikes a ball of mass $0.15$ kg moving at $20$ m/s, sending it back at $20$ m/s. The impulse on theA gun of mass $4$ kg fires a bullet of mass $0.04$ kg at $300$ m/s. Recoil speed of the gun is:A book sliding across a smooth wooden desk gradually slows and stops. The force responsible is:
