Practice ICSE Class 9 Laws of Motion in the app →Newton's first law of motion describes:The SI unit of linear momentum is:Which is a non-contact force?The SI unit of force is the newton. One newton equals:Which form of Newton's second law of motion is most general?A body of mass 2 kg starts from rest and reaches 6 m per second in 3 s. The applied force is:A 100 g bullet leaves a gun with a velocity of 200 m per second. The bullet's momentum is:A boy jumps off a moving bus and falls forward. The reason is:A rocket moves forward by expelling gases backward. This is an application of:When a cricketer lowers his hands while catching a ball, the force on his hands:Two bodies have equal momentum. Which one has the LARGER kinetic energy?A 0.2 kg ball moving at 10 m per second is brought to rest in 0.05 s. The average force on the ball is:A 1000 kg car is brought to rest in 5 seconds from 20 m per second. The braking force needed is:A man weighs 60 kgf on Earth. His weight in newtons is:A gun of mass 4 kg fires a 0.02 kg bullet at 200 m per second. By conservation of momentum, the recoil velocit
