A ball is thrown straight up with an initial speed of 12 m/s. What are the velocity and acceleration when it is at the top of its trajectory? Select all apply. v = 12 m/s a = 0 O v = 0 v = -12 m/s a = 9.8 m/s2 a = -9.8 m/s2
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.
In a projectile motion:
The object starts from zero and reaches the highest point of the trajectory.
After reaching the highest point, it starts coming towards the ground.
Formula used:
a =
here, a is the acceleration, v is the velocity and is the change in the velocity.
