Motion in a straight line (quick revision formula)

Motion in a straight line is a fundamental concept in physics that involves the study of the motion of objects along a straight path. Here are some quick revision formulas to help you understand this concept better:




Distance, Displacement, and Speed
- Distance is the total length of the path traveled by an object.
- Displacement is the change in position of an object from its initial point to its final point.
- Speed is the rate at which an object covers distance.




Velocity and Acceleration
- Velocity is the rate of change of displacement with respect to time.
- Acceleration is the rate of change of velocity with respect to time.




Equations of Motion
- First equation of motion: v = u + at, where v is final velocity, u is initial velocity, a is acceleration, and t is time.
- Second equation of motion: s = ut + (1/2)at^2, where s is displacement.
- Third equation of motion: v^2 = u^2 + 2as.




Graphs of Motion
- A distance-time graph shows how the distance traveled by an object changes over time.
- A velocity-time graph shows how the velocity of an object changes over time.
- The slope of a distance-time graph gives the speed of the object.

These quick revision formulas will help you understand the basic principles of motion in a straight line and solve problems related to this topic more effectively.
