The inner ear's vestibular system is responsible for detecting linear acceleration, which includes changes in motion like speeding up or slowing down. Gravity is sensed by the otolith organs within the vestibular system, specifically the utricle and saccule, which detect changes in head position and orientation relative to gravity.

What are similarities of uniform linear acceleration to acceleration due to gravity?
Both uniform linear acceleration and acceleration due to gravity involve constant acceleration which causes an increase in velocity over time. They both follow the laws of motion described by Newton's second law, where acceleration is proportional to the force applied. In both cases, the rate of change in velocity is constant.
Your perception of the pull of gravity and linear acceleration is the result of?
The perception of the pull of gravity and linear acceleration is the result of the forces acting on objects. Gravity causes objects to be attracted to the center of mass of another object (like the Earth), while linear acceleration results in a change in an object's velocity over time. These forces can be felt by objects and cause them to move in a predictable manner.
What is the relationship between linear and angular acceleration in rotational motion?
In rotational motion, linear acceleration and angular acceleration are related. Linear acceleration is the rate of change of linear velocity, while angular acceleration is the rate of change of angular velocity. The relationship between the two is that linear acceleration and angular acceleration are directly proportional to each other, meaning that an increase in angular acceleration will result in a corresponding increase in linear acceleration.
What is the relationship between the angular acceleration formula and linear acceleration in rotational motion?
The angular acceleration formula is related to linear acceleration in rotational motion through the equation a r, where a is linear acceleration, r is the radius of rotation, and is angular acceleration. This equation shows that linear acceleration is directly proportional to the radius of rotation and angular acceleration.
How does the angular acceleration of a rotating object relate to its linear acceleration?
Angular acceleration and linear acceleration are related through the radius of the rotating object. The angular acceleration is directly proportional to the linear acceleration and inversely proportional to the radius of the object. This means that as the linear acceleration increases, the angular acceleration also increases, but decreases as the radius of the object increases.
Gravity and linear acceleration are sensed in the?
Gravity and linear acceleration are sensed in the inner ear's vestibular system. The vestibular system detects changes in head position and movement, providing information to the brain about spatial orientation and balance. This information is crucial for maintaining stability and coordinating body movements.
What detects linear acceleration in the ear?
The utricle and saccule in the inner ear are responsible for detecting linear acceleration such as changes in head positioning and forward/backward movements. They contain specialized sensory cells called hair cells that detect these movements through the movement of tiny calcium carbonate crystals called otoliths.
Why do you calculate center of gravity?
If a force acts in a direction which passes through the centre of gravity of the object then it will impart no rotational acceleration; only linear acceleration.
Is a constant acceleration graph a linear equation?
Not necessarily. The equation of a projectile, moving under constant acceleration (due to gravity) is a parabola - a non-linear equation.
Do otoliths detect linear acceleration?
Yes. A gelatinous cover, over tiny hairs in the saccule, which contain otholiths (ear stones) detects acceleration when they are bent during this movement.

Angular acceleration and linear acceleration are related in a rotating object through the equation a r, where a is linear acceleration, r is the radius of the object, and is the angular acceleration. This equation shows that the linear acceleration of a point on a rotating object is directly proportional to the angular acceleration and the distance from the center of rotation.
