A baseball is thrown up into the air, reaches a peak, then comes back down. At the very peak of its arc, what is the ball's acceleration? Explain your answer
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.
A baseball is thrown up into the air, reaches a peak, then comes back down. At the very peak of its arc, what is the ball's acceleration? Explain your answer.
In a projectile motion , the only force acting on the object will the gravitational force acting downwards . This means the object has constant horizontal velocity and it's vertical velocity changes under the acceleration due to gravity , .
In the projectile path , as the object is moving up , the velocity of the object will decrease ,as the acceleration due to gravity is acting opposite to the velocity direction , so deceleration will be acting . As the object reaches the maximum height , the velocity will be zero, but there will be still acceleration , which is the acceleration due to gravity . Then as the projectile goes down , the velocity will increase as the acceleration due to gravity will be acting along the direction of the velocity .
