Athletes have to run the heats and they rest their foot on a solid supports before start so that during the start of the race the athlete pushes the s...
A vehicle moving on mountains is in the inertia of motion. At a sudden turn there is a tendency of vehicle to fall off the road due to sudden change i...
Momentum of two bodies before collision is equal to the momentum after collision. In an isolated system, the total momentum remain conserved.
A karate player applied the blow with large velocity in a very short interval of time on the ice slab which therefore exerts large amount of force on ...
In a high jump athletic event, athletes are made to fall either on a cushioned bed or on a sand bed so as to increase the time of the athlete’s fall t...
While catching a fast moving cricket ball, a fielder on the ground gradually pulls his hands backwards with the moving ball. This is done so that the ...
While moving in a bus our body is in motion. On jumping out of a moving bus our feet touches the ground and come to rest. While the upper part of our ...
It is due to law of inertia. When we are sitting in car moving in straight line, we tend to continue in our straight-line motion. But when an unbalanc...
Force can bring following changes in the body: It can change the speed of a body. It can change the direction of motion of a body. It can change...
Balanced force 1. Forces acting on a body from the opposite direction are same. 2. It does not change the state of rest or of motion of an object....
The forces A, B, C and D acting on the truck are: A → driving force B → reacting force C → frictional force D → weight/gravitational force
The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.
Two factors on which momentum of a body depend is mass and velocity. Momentum is directly proportional to the mass and velocity of the body.
Inertia of a body depends upon the mass of the body.
A body of mass 20 kg will have more inertia.
To every action, there is an equal and opposite reaction and they act on two different bodies.
The momentum of an object is the product of its mass and velocity and has the same direction as that of the velocity. The S. I. unit is kg m/s. (p = m...
The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.
An object remains in a state of rest or of uniform motion in a straight line unless acted upon by an external unbalanced force.
The natural tendency of an object to resist a change in their state of rest or of uniform motion is called inertia.
