How can we predict a soccer ball's flight path using Newton's laws?
What force of attraction is keeping the soccer ball at the bottom of the ditch? The force of gravity is keeping the football in the ditch . player is trying to …
What is the center of gravity for a soccer ball?
May 13, 2021 · This slide shows the three forces that act on a soccer ball in flight. The forces are shown in blue and include the weight, drag, and lift or side force. Lift and drag are actually two components of a single aerodynamic force acting on the ball. In the figure, the ball is moving from the upper right to the lower left (in perspective), as indicated by the red arrow.
What is the lift force on a soccer kick?
player is trying to kick a ball out of a ditch. a) What force of attraction is keeping the football at the bottom of the ditch? The force of gravity is keeping the football in the ditch.
Which type of energy must the ball have to get out of the ditch potential or kinetic?
kinetic energyThe ball must have kinetic energy if it is to get out of the ditch.
What force of attraction holds the electron in the hydrogen atom?
Coulombic attractionWhat force of attraction holds the electron in the hydrogen atom? There is Coulombic attraction between the positively-charged nucleus and the electron.
What does the photoelectron spectrum show?
Photoelectron spectroscopy (PES) is an experimental technique that measures the relative energies of electrons in atoms and molecules. Scientists often use PES to study the elemental composition of materials or to characterize bonding in molecules.
What is supplying the energy to remove the electron from the atom?
ionization energy, also called ionization potential, in chemistry and physics, the amount of energy required to remove an electron from an isolated atom or molecule.
What force holds atom together?
So the nucleus of an atom is held together by the strong force, while the electrons are held in the atom by the electric force.
Which force holds electrons in an atom Brainly?
The electromagnetic force keeps the electrons attached to the atom. The strong force keeps the protons and neutrons together in the nucleus.Jul 30, 2020
What is HF photoelectric effect?
The energy of each photon is E = hf, where h is Planck's constant and f is the frequency of the EM radiation. Higher intensity means more photons per unit area.

What is the ability to attract electrons for bonding?
electronegativityThe ability of an atom to attract electrons in a chemical bond is called the electronegativity of the atom. The electronegativity of an atom is related to its electron affinity and ionization energy.
What is the energy required to remove an electron from an atom in a gaseous state?
The energy required to remove an electron from an atom in the gaseous state is called ionization energy.
What are the forces that affect a soccer ball?
This slide shows the three forces that act on a soccer ball in flight. The forces are shown in blue and include the weight, drag, and lift or side force . Lift and drag are actually two components of a single aerodynamic force acting on the ball. In the figure, the ball is moving from the upper right to the lower left (in perspective), ...
What causes a soccer ball to move erratically?
So the center of pressure for a soccer ball moves slightly about the center of the ball with time, depending on the orientation of the stitches. The time-varying aerodynamic force causes the ball to move erratically.
How to determine drag on a soccer ball?
For a soccer ball, the drag can be determined experimentally by throwing the ball at a measured speed and accurately measuring the change in velocity as the ball passes between two points of known distance. Lift. Lift is the component of the aerodynamic force that is perpendicular to the flight direction.
What is the component of aerodynamic force that is perpendicular to the flight direction?
Lift is the component of the aerodynamic force that is perpendicular to the flight direction. Airplane wings generate lift to overcome the weight of the airplane and allow the airplane to fly. A rotating cylinder and a spinning ball also generate aerodynamic lift .
Why is it so hard to determine the magnitude of drag force?
Determining the magnitude of the drag force is difficult because it depends on the details of how the flow interacts with the surface of the object. For a soccer ball, this is particularly difficult because stitches are used to hold the ball together. So the surface of the ball is not smooth.
What are the factors that affect the magnitude of drag force?
In general, there are many factors that affect the magnitude of the drag force including the shape and size of the object, the square of the velocity of the object, and conditions of the air; particularly, the density and viscosity of the air.
What is the force of gravity in flight?
In flight, the ball rotates about the center of gravity. Newton's laws of motion describe the translation of the center of gravity. As the ball moves through the air, the air resists the motion of the ball and the resistance force is called drag . Drag is directed along and opposed to the flight direction.
