Why is it called scalar?

The word scalar derives from the Latin word scalaris, an adjectival form of scala (Latin for “ladder”), from which the English word scale also comes. What is scalar mean in physics? Scalar quantities are those that can be described with magnitude only, as opposed to vectors, which include both magnitude and direction components. Distance, speed, … Read more

What is the definition of magnitude in science?

The magnitude is a number that characterizes the relative size of an earthquake. Magnitude is based on measurement of the maximum motion recorded by a seismograph. What is a simple definition of magnitude? The term magnitude is defined as “how much of a quantity”. For instance, the magnitude can be used for explaining the comparison … Read more

What is the best definition for mass?

mass. [ măs ] A measure of the amount of matter contained in or constituting a physical body. In classical mechanics, the mass of an object is related to the force required to accelerate it and hence is related to its inertia, and is essential to Newton’s laws of motion. What is a easy definition … Read more

What is force definition in physics?

When a metal spring is stretched or compressed, it is displaced from its equilibrium position. As a result, it experiences a restoring force that tends to retract the spring back to its original position. This force is called the spring force. It is a contact force that can be found in elastic materials. What is … Read more

What does velocity mean simple definition?

The first law of motion states that a body will remain at rest, or continue at a constant velocity, unless a force is applied. Essentially, velocity is always constant in this law. At rest, velocity remains zero. While in motion, velocity remains the same until a force is applied. What is velocity definition in physics? … Read more

What is mass and matter?

Matter is all the “stuff” that exists in the universe. It has both mass and volume. Mass measures the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg). What is a easy definition of mass? Mass (symbolized m) is a dimensionless quantity representing the amount … Read more

What is a vector simple terms?

Definition of a vector. A vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. What is a vector in physics? vector, in physics, a quantity that … Read more

What is impulse for kids physics?

What is impulse vs momentum? The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it. The impulse-momentum theorem is logically equivalent to Newton’s second law of motion (the force law). What is impulse with example? You use the concept of impulse in your everyday life without even … Read more

What is physics and its types?

The science branch of science which deals with the interaction of energy and matter is called physics. There are Two Major Branches of Physics that are Modern and Classical Physics. Further physics sub branches are electromagnetism, Mechanics, Thermodynamics, Optics. What is a simple definition of physics? Definition of physics 1 : a science that deals … Read more

What is inertia definition and example?

Inertia resists change in motion. Objects want to stay in rest or motion unless an outside force causes a change. For example, if you roll a ball, it will continue rolling unless friction or something else stops it by force. What is inertia and types? Types of Inertia It is of three types: The inertia … Read more
