Chapter 3: Motion Along a Straight Line in Physics

Question

• Acceleration due to gravity: acceleration of an object as a result of gravity.
• Average acceleration: the rate of change in velocity; the change in velocity over time.
• Average speed: the total distance traveled divided by elapsed time.
• average velocity: the displacement divided by the time over which displacement occurs under constant acceleration. 
• Displacement: the change in position of an object.
• Distance traveled: the total length of the path traveled between two positions
• elapsed time: the difference between the ending time and the beginning time.
• free fall: the state of movement that results from gravitational force only
• instantaneous acceleration: acceleration at a specific point in time
• instantaneous speed: the absolute value of the instantaneous velocity.
• instantaneous velocity: the velocity at a specific instant or time point
• kinematics: the description of motion through properties such as position, time, velocity, and acceleration.
• position: the location of an object at a particular time
• total displacement: the sum of individual displacements over a given time period
• two-body pursuit problem: a kinematics problem in which the unknowns are calculated by solving the kinematic equations simultaneously for two moving objects
