reaction around aforce

Hook two spring balances as shown in the diagram and pull from either side. You will notice that the pointers on the spring balances read equally (say 100 N). This shows that both the spring balances are registering equal force. Blow a balloon and hold its neck tightly facing downward. W..

Introduction - Pushes or Pulls are very general names given to forces. A physicist is much more precise when describing forces acting on a body using terms like weight, frictional force, tension, normal reaction force, electrical force, ma..

Summary - Force produces or prevents motion of a body. Friction is a force that opposes motion. Moment is defined as the turning effect of a force about a pivot or fulcrum. The centre of gravity of a body is a point where the whole weight of the body seems to be concen..

The forces on the space-shuttle are similar to the forces in a collision between two tennis balls. When the balls collide, they are propelled in opposite directions. The rockets of the space-shuttle force burning gases downward through the exhaust vents. In response t..

It can be summarized that the spontaneous processes occur because of the two tendencies: (i) Tendency of a system to acquire a state of minimum energy. (ii) Tendency of a system to acquire a state of maximum randomness. The overall tendency for a process to take place by itself is called the drivi..

f is the horizontal component of the reaction experienced by the horse's leg when it applies an inclined thrust on the ground. Hence, it is in the forward direction. Net force on horse = f-F 1 Mass of horse = m H Since the horse and cart move together, acceleration of cart ..

Imagine that you are watching a volleyball match and suddenly the ball comes towards you. Due to your reflexes you hit the ball so that you do not get hurt. The ball moves away from you due to the action of your hand on it. But definitely your hands pain due to the impact of the ball. That is, when..

The law of conservation of momentum states that the total vector sum of momenta of bodies, in an isolated system, along any straight line remains conserved and remains unchanged due to reaction forces between the forces of the syste..

Sliding friction opposes the applied force and has a constant value. Normal reaction and force of sliding friction are proportional quantities. Keeping normal reaction constant, the frictional force is independent of the surface area in cont..

Pushes or Pulls are very general names given to forces. A physicist is much more precise when describing forces acting on a body using terms like weight, frictional force, tension, normal reaction force, electrical force, magnetic for..
