The forces that propel a volleyball forward and over the net behave in the manner explained by all three of Newton's laws of motion. The net force contributes to both the start and finish of the ball's movement.
According to the first law of motion, the ball does not move when no forces are acting on it and the net force is zero. The second part of Newton's first law of motion explains that the ball can remain in motion only as long as it meets no opposing forces. While a serve begins the movement of a volleyball, such factors as gravity and air resistance slow and eventually stop the movement of the ball.
The second law of motion explains the relationship between mass, acceleration and force. In volleyball, a ball has a faster acceleration when it receives a forceful hit. A more massive ball requires a more forceful hit to travel at the same rate of acceleration as a smaller ball.
Newton's third law of motion explains that every force has an opposing force. When a volleyball player forcefully hits a volleyball, the ball exerts an equal force on the player. That force can be the cause of redness or pain from hitting a ball.Learn More
Newton's First Law of Motion defines the concept of inertia. The law states that an object will remain in its original state of motion until acted upon by an outside force.Full Answer >
The ramp, wedge and screw are simple machines belonging to the inclined plane family. Inclined planes makes it easier to move an object. Lifting an object vertically requires a great amount of force. Using a ramp requires less force, but also requires the object to be moved a greater distance.Full Answer >
For a rigid body to be in static equilibrium, without total acceleration, two conditions must be met. First, the vector sum of all forces acting on it must be zero (translational equilibrium). Second, the sum off all torques due to any external force on any axis must be zero (rotational equilibrium).Full Answer >
The force responsible for causing air movement is known as pressure gradient force. To display wind speeds, the pressure gradient is plotted onto a weather map using isobars that are mapped between areas of low and high pressure.Full Answer >
