Understanding Scalar, Vector and Distance Terms

Click For Summary
Distance is a scalar quantity that measures how much ground is covered without regard to direction, while displacement is a vector quantity that includes both distance and direction. Scalars are defined by a magnitude alone, such as temperature or speed, while vectors require both magnitude and direction, like wind velocity or gravitational force. Velocity is indeed a vector that describes speed in a specific direction, often measured in units like kilometers per hour. Understanding these distinctions is crucial for grasping concepts in physics and related fields. Clarity on these terms enhances comprehension of motion and measurement in various contexts.

Could you please help me understand how these terms relate to one another?

Scalar, Vector, Displacement, Distance, Speed, Velocity, Accelaration, Position?

So Distance is a scalar Quantity, what is a Scaler? Displacement is a vector quantity, what is a Vector? Is velocity just the unit like kilometres per hour? Speed is the distance traveled and doesn't require a direction.

I need to know these terms.

A scalar is anything that you can measure that just needs a number. Examples of a scalar are temperature, your age, how much money you have in the bank, how fast your car goes.

A vector is anything that needs a number and a direction to tell you examples are the wind velocity, the force of gravity, where the Sun is.

So yes, your last statement is correct.
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
