What are the key characteristics of objects in horizontal circular motion?
Objects in horizontal circular motion experience a centripetal force that keeps them moving in a circular path. They have a constant speed but changing velocity due to the direction of their motion. Additionally, they experience acceleration towards the center of the circle, known as centripetal acceleration.
What are examples of centipetal acceleration?
Examples of centripetal acceleration include a car moving around a curve, a spinning top, or a satellite orbiting around Earth. These objects experience centripetal acceleration because their velocity is constantly changing direction towards the center of the circular path they follow.
What is the concept of acceleration in physics and how does it relate to the motion of objects?
Acceleration in physics is the rate of change of an object's velocity over time. It measures how quickly an object's speed is changing. Acceleration is directly related to the motion of objects because it determines how fast an object is speeding up or slowing down. Objects with a higher acceleration will change their velocity more rapidly than objects with a lower acceleration.
Does the law of acceleration apply to objects having circular motion?
No, the law of acceleration does not apply to objects in circular motion. Instead, objects in circular motion follow the principles of centripetal acceleration and centripetal force, which keep the object moving in its circular path.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.

How an objects be motionless and in equilibrium?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.

What forces can affect an objects velocity but not the speed?
Centripetal forces can.

What is the rate of change and of speed and direction?
acceleration
Is it possible for an objects velocity to be perpendicular to the objects acceleration?
no
What is the type of force that keeps objects moving in a circle or an arc?
The type of force that keeps objects moving in a circle or an arc is called centripetal force. It acts towards the center of the circular path and is responsible for changing the direction of the object's velocity without changing its speed.
What is necessary to keep objects moving in circular motions?
A centripetal force is required - something that pushes the object towards the center. This is in accordance with Newton's Second Law - to have an acceleration (which includes a change of velocity), a force is required.
What is the objects acceleration?
The acceleration of an object is the rate at which its velocity is changing over time. It is a vector quantity, meaning it has both magnitude and direction. Acceleration can be positive, negative, or zero, depending on whether the object is speeding up, slowing down, or maintaining a constant velocity.
