Yes, a person jogging at 3 m/s along the wind can be considered an example of acceleration if there is a change in velocity, such as increasing speed, changing direction, or experiencing a change in wind resistance. Acceleration is defined as the rate of change of velocity over time. If the jogger maintains a constant speed and direction, then there is no acceleration. However, if the wind affects their speed or direction, then acceleration occurs.
What else can I help you with?
What is the direction of the acceleration vector of a person on spinning earth?
The acceleration vector of a person on spinning Earth points towards the center of Earth due to gravity. Additionally, this acceleration vector is perpendicular to the direction of the person's velocity as they move along Earth's surface.
What is the example where acceleration is in the direction of motion?
An example of acceleration in the direction of motion is a smooth spherical stone dropped from the roof of a building on a windless day. All the motion is straight down, toward the center of the earth, and so is the acceleration.
Does a person riding a Ferris wheel accelerate?
Yes, a person riding a Ferris wheel experiences acceleration. Even though the speed of the person may remain constant, the direction of their velocity is constantly changing as they move along the circular path, resulting in centripetal acceleration.
A person is on an elevator that moves downward with an acceleration of 1.8 ms squared. If the person weighs 686 n what is the net force on the person?
The net force on the person can be calculated using Newton's second law: F = m * a, where F is the net force, m is the mass of the person, and a is the acceleration. The weight of the person can be converted to mass using the formula weight = mass * acceleration due to gravity (9.8 m/s^2). Once you have the mass, you can plug it into the formula along with the given acceleration to calculate the net force.
What is the difference between radial and tangential acceleration in circular motion?
Radial acceleration is the acceleration towards the center of the circle, while tangential acceleration is the acceleration along the tangent to the circle.
What is the difference between radial and tangential acceleration?
Radial acceleration is the acceleration towards the center of a circular path, while tangential acceleration is the acceleration along the direction of motion in a circular path.
What is the difference between centripetal acceleration and tangential acceleration in circular motion?
Centripetal acceleration is the acceleration directed towards the center of a circular path, while tangential acceleration is the acceleration along the tangent of the circle, perpendicular to the centripetal acceleration.
What is the difference between centripetal and tangential acceleration in circular motion?
Centripetal acceleration is the acceleration directed towards the center of the circle in circular motion, while tangential acceleration is the acceleration along the tangent to the circle.
Is linear acceleration the same as the tangential acceleration in circular motion?
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.
What is an example of tangential and centripetal acceleration?
If an object follows a circular path, it must have a centripetal force on it to keep it moving in a circle. Centripetal means "toward the center of the circle". The force causes Centripetal acceleration toward the center witch is along the radius of the circular path. Tangential acceleration occurs at a Tangent to the circular path and is always perpendicular to the centripetal acceleration. Always perpendicular to the radius of the circle.
What is meant by centripetal acceleration is perpendicular to velocity?
As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
What is the difference between radial acceleration and tangential acceleration in the context of circular motion?
Radial acceleration is the acceleration towards the center of a circle, while tangential acceleration is the acceleration along the edge of the circle. Radial acceleration changes the direction of velocity, while tangential acceleration changes the magnitude of velocity in circular motion.
