A car is moving at 45 km/hr.A constant force acts on the car for 10 sc .So that it's velocity becomes 63 km/hr.The distance travelled by car during this interval of 10 sec is :
Rocket works on the principle of conservation of
An object of mass 2 kg is sliding with a constant velocity of 4 m/ s on a frictionless horizontal table. The force required to keep the object moving with the same velocity is
There will be a change in the speed or in the direction of motion of a body when it is acted upon by
Qualitative definition of Force is given by
Formula to find the Force is
The action and reaction forces referred to in the third law
An example of a body moving with constant speed but still accelerating is
A bullet of mass 20gm is fired from a gun of mass 8kg with a velocity of 400m/s, calculate the recoil velocity of gun
A hammer of mass 500 g, moving at 50m/s, strikes a nail. The nail stops the hammer in a very short time of 0.01 s. The force of the nail on the hammer is
Acceleration acts always in the direction
A body of weight W is suspended from the ceiling of a room through a rope of weight R. The ceiling pulls the rope by a force of
Newtons laws do not hold good for particles
1st law of motion gives the definition of
