The motion of an object is defined as the change in position of the object with respect to time. And, Kinematics refers to comparison and classification of motion.
To locate the position of an object, we need a reference point. Mostly, we consider the reference point at the origin.
In the above diagram, point O is the origin. And, the positive direction is on the right side. Also, the negative direction would be on the left side.
Displacement is the shortest distance possible between the start and end point.
is the displacement between position and .
Average velocity could be calculated by taking the ratio of displacement and time interval. It depends upon the direction of motion.
Average speed would be the ratio of total distance covered and time interval .
Acceleration could be calculated by taking the ratio of change in velocity and time interval .
The following equations are true for the constant acceleration.
Question 1: Calculate the displacement between location , and location
Explanation: Let is the displacement between position and .
And, we have ,
Final answer: The displacement would be 7 meters.
Question 2: Calculate the velocity of an object after , with a constant acceleration of . Initially, the object was at rest.
Explanation: We will use the equation of motion .
Final answer: The velocity of the object would be
Question 3: The total distance covered by John during a 17-minute walk is 1.5 km. Calculate the average speed of John in m/s.
Explanation: We will use conversion to rewrite the given details in the SI unit.
17 minutes would be .
And, 1.5 km would be
Now, let us plug the total distance and time interval.
Final answer: The average speed of John would be .
In Physics, Motion can be defined as a change in position of an object with reference to time and is a simplest part of Classical mechanics.
