I guess it is how long to travel the distance. I copied the exact question I got.bhillyard said:What distance to come to a stop?
How much of the 150 m is left?
How long to travel that distance?
Kinematics is the branch of classical mechanics that deals with the motion of objects without considering the forces that caused the motion. It involves studying the position, velocity, and acceleration of objects over time.
The three equations of kinematics are:
1. v = u + at (equation for velocity)
2. s = ut + 1/2at^2 (equation for displacement)
3. v^2 = u^2 + 2as (equation for final velocity)
Velocity is the rate of change of an object's displacement, while acceleration is the rate of change of an object's velocity. In simpler terms, velocity measures how fast an object is moving, while acceleration measures how quickly the object's speed is changing.
Average velocity is the total displacement of an object divided by the total time taken. It gives an overall picture of an object's motion. Instantaneous velocity, on the other hand, is the velocity of an object at a specific moment in time. It is calculated by taking the limit as the time interval approaches zero.
Motion can be represented on a velocity-time graph by plotting the velocity on the y-axis and time on the x-axis. A straight line on the graph represents constant velocity, while a curved line represents changing velocity. The slope of the line represents the acceleration of the object.
