Strength of Acids and Bases

"The strength of acids and bases depend on how much an acid or base ionizes in solution. A strong acid or base completely ionizes in solution. In a neutralization reaction, an acid and  a base react ...

Force

"A force is defined in physics as anything that affects an object's acceleration. A force is a vector quantity because it has both magnitude and direction. The unit for force is the Newton (N) or kg/m ...

Centripetal Force

"Centripetal force causes an object in motion to continue in a curved path rather than a linear one. If this force stops, the object will continue in a tangential linear path. An example of centripeta ...

Centrifugal Force

"Many students call centripetal force centrifugal force, but the two are not the same. Centrifugal force is the reaction to centripetal force as explained by Newton's Third Law of Motion, but it is on ...

Buoyancy

"Buoyant force is the force that a fluid exerts on a object that is immersed within it. It is called buoyant force because this force is a lifting force, often making the object buoyant. Buoyant force ...

Lorentz Force

"Lorentz force is the force on charge in electromagnetic field. Lorentz force is determined by the formula F = qv x B, in which q is the charge, v is the velocity, and B is the magnetic field density. ...

Law of Force and Acceleration - Newton's Second Law of Motion

"According to Newton’s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. S ...
