Answer #1:
Free fall is motion due to gravity.
centripetal force causes the acceleration in a circular motion.
===========================
Answer #2:
"Acceleration" means a change in either the speed or the direction of motion.
(Or both, of course.)
Maintaining a steady 30 miles per hour as you round a curve is acceleration.
In the case of free fall, the speed is constantly increasing.
In the case of circular moltion, the direction is constantly changing, and the speed could also be.
No, linear acceleration refers to changes in speed along a straight line, while tangential acceleration refers to changes in speed along the circumference of a circle in circular motion. In circular motion, objects experience both tangential and centripetal accelerations.
Both projectile motion and circular motion involve the motion of an object in a curved path. In projectile motion, the object follows a curved path due to the influence of gravity, while in circular motion, the object moves in a circle with a constant radius. Both involve centripetal acceleration that changes the direction of the object's velocity without changing its speed.
Acceleration is identified by any change in an object's speed, direction, or both. This can be observed by an increase or decrease in speed, a change in direction, or both. Acceleration is a vector quantity, meaning it has both magnitude (amount) and direction.
In rotational motion, acceleration is related to angular acceleration because they both measure how quickly an object is speeding up or slowing down in its circular motion. Acceleration measures the change in linear speed, while angular acceleration measures the change in rotational speed. Both are affected by the force applied to the object and the object's moment of inertia.
Motion can be classified into four types based on changes in direction and speed: Rectilinear motion: Motion along a straight line with constant speed. Uniform circular motion: Motion in a circular path at a constant speed. Accelerated motion: Motion with a change in speed but moving in a straight line. Curvilinear motion: Motion with changes in both speed and direction, following a curved path.

Circular motion and variable motion are alike because both of them are constant. Another way they're alike is that variable motion is used with transportation movements like cars, trucks, and buses. Circular motion can also be used with transportation like with wheels on cars, trucks, and buses.

Linear motion is motion in a straight line, such as a dragster heading down the track, or a person walking down the sidewalk. Circular motion is motion in a circle, such as a yo-yo swung around someones head, or a car making a turn. In physics, while these two categories of motion exist, in most cases outside textbook examples, an objects motion will include both types of motion at once.
Uniform circular motion describes motion in which an object moves with constant speed along a circular path.In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel. This changing velocity indicates the presence of an acceleration; this centripetal acceleration is of constant magnitude and directed at all times towards the axis of rotation. This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation.
Yes. Acceleration is the change in velocity, and velocity is a vector, which means it has direction. Because an object undergoing uniform circular motion is changing direction, it is changing velocity, and thus, accelerating.
The motion of an athlete moving along a circular path is considered accelerated because even if the speed remains constant, the direction of the athlete's velocity is constantly changing. Acceleration is defined as a change in velocity, which includes changes in speed, direction, or both. In this case, the constant change in direction as the athlete moves along the curved path results in an acceleration towards the center of the circle, known as centripetal acceleration.
Yes, a projectile can have both radial (centripetal) acceleration and tangential (linear) acceleration. The radial acceleration is directed towards the center of the circular path the projectile follows, while the tangential acceleration is along the direction of motion. Together, these accelerations determine the projectile's overall acceleration as it moves through its trajectory.
"Acceleration" is the term used to describe motion whose speed, or direction, or both, are changing.
