Pulling forces and rubber bands- Slowly stretch a rubber band and think about what you are doing. Most people use two hands placed at opposite ends of the rubber band and pull with each hand away from each other. This means there are two pulling forces acting on the rubber band in opposite directions. Now try to stretch the rubber band by using one hand and by grabbing the rubber band at only one place. We know it's possible to stretch the rubber band with one hand using your thumb and finger at two different places but can you figure out a way to stretch the rubber band by applying the force at only one place? If you hooked the rubber band over something to stretch it, is there only one force acting at only one place
for every action there is a reaction so this is the force.
The net force on the ball is not zero. The ball exerts a force on the wall (the action), and the wall exerts an equal and opposite reaction force on the ball. These two forces do not sum to zero as they are acting on different objects; the action of the ball acts on the wall and the reaction of the wall acts on the ball.
Unbalanced forces are important in order to move anything. An object under balanced forces does not move. For example as you sit in your chair reading this, gravity is exerting a force on your body downwards but your chair balances this force by exerting a force upwards on you that is equal and opposite to the force of gravity. These two forces oppose each other and therefore you do not move. In tennis in order to change the direction of a tennis ball you need to exert a net force(an unbalanced force) in the direction you want the tennis ball to move. In tennis there are also unbalanced torques(a force acting at a distance from a pivot point) on the ball that cause the ball to spin. Hope that helps.
Inthe kicking force, kinetic energy is acting on the ball together with Gravitational Potential Energy. Whereas the part where aother force is acting on iit while the ball is not moving is alsoocontrolled by gravitaitional potential energy.
Yes, a ball is in equilibrium at the top of it's throw because there is a moment of no change, or equilibrium, when it is suspended in air.
Equal.
Yes
Either there are none, or if there are any, then the whole group of forces is balanced.
no
salt
Gravity, force, and acceleration.
gravity, buoyancy, surface tension.
When i hit a ball i.e. we give a force in the ball,the ball give an equal & opposite force in our hand..as the two forces acting in the two different bodies so the equal and opposite forces cannot balance with each other..
no,,, the ball pen is at rest or meaningful is sleep,,,thers no motion or forces acting on the ball pen when it hanging on to the yarn,,,,,,
Net force is the addition of all forces applied. An example would be a still ball (a ball not in motion). The ball would be in "equilibrium" meaning that the ball is at rest, therefore, the net force of this ball would be 0.
for every action there is a reaction so this is the force.
The net force on the ball is not zero. The ball exerts a force on the wall (the action), and the wall exerts an equal and opposite reaction force on the ball. These two forces do not sum to zero as they are acting on different objects; the action of the ball acts on the wall and the reaction of the wall acts on the ball.
