could be responsible for the difference between your measured and predicted values for the horizontal distance traveled by the projectile at the different angles used in this experiment. “Human error” is not acceptable without saying specifically what error the human could have made. “Calculation error” is also not acceptable—if you are worried about whether the calculation is correct, consult with your classmates and/or someone you trust to do the calculation correctly.
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
