Time

Time, abbreviated as t, is a fundamental concept in physics and is often described as the fourth dimension.  It is a dimension in which events occur in a sequence, from the past through the present and into the future.  In physics, time is often considered to be relative and can be affected by factors such as gravity and velocity.  The passage of time can be measured using various methods, such as with a clock or with the decay of radioactive materials.

In physics, time can be used to describe the motion of objects, the behavior of waves, and the evolution of physical systems.  The concept of time is also important in many other fields, including philosophy, biology, and psychology.  It is a fundamental part of human experience and plays a crucial role in our understanding of the world around us.

 

time with Displacement formula
\( t \;=\; d  \;/\; s \)     (Time with Displacement) \( d \;=\; t \; s  \) \( s \;=\; d  \;/\; t \)
Symbol	English	Metric
\( t \) = Time	\(sec\)	\(s\)
\( d \) = Displacement	\(ft\)	\(m\)
\( s \) = Speed	\(ft \;/\; sec\)	\(m \;/\; s\)

 

time with Power formula
\( t \;=\;   F \; d \;/\; P \)     (Time with Power) \( F \;=\; t \; P \;/\; d \) \( d \;=\; t \; P \;/\; F \) \( P \;=\; F \; d \;/\; t \)
Symbol	English	Metric
\( t \) = Time	\(sec\)	\(s\)
\( F \) = Force	\(lbf\)	\(N\)
\( d \) = Displacement	\(ft\)	\(m\)
\( P \) = Power	\(W\)	\(kg-m^2 \;/\; s^3\)

 

time with Work formula
\( t \;=\;   W \;/\; P \)     (Time with Work) \( W \;=\; t \; P  \) \( P \;=\; W \;/\; t \)
Symbol	English	Metric
\( t \) = Time	\(sec\)	\(s\)
\( W \) = Work	\(lbf-ft\)	\(J\)
\( P \) = Power	\(W\)	\(kg-m^2 \;/\; s^3\)
