What else can I help you with?
What two things do velocity include?
Velocity includes speed, which refers to the rate at which an object changes position, and direction, which indicates the path an object is traveling along.
What is the rate of change of velocity with distance called?
The rate of change of velocity with distance is called acceleration. It measures how velocity changes over time as an object moves along its path.
What is tangential velocity and tangential acceleration?
Tangential velocity is the component of velocity that is perpendicular to the radial direction in circular motion. It represents the speed at which an object is moving along the circular path. Tangential acceleration is the rate at which the tangential velocity of an object changes, causing the object to speed up or slow down in its circular motion.
Describe the trajectory for horizontally fired projectiles along an incline .sketch the trajectory?
When a projectile is fired horizontally along an incline, the horizontal component of its velocity causes it to move along the incline while the vertical component of its velocity causes it to rise and fall. The trajectory will be a curved path that follows the incline uphill before falling back down. The range of the projectile will depend on its initial velocity and the angle of the incline. Unfortunately, I'm unable to provide a sketch here.
Does velocity of an object remain constant in uniform circular motion?
No, the velocity of an object in uniform circular motion is not constant because although the speed may remain constant, the direction of the velocity continuously changes as the object moves along the circular path. This change in direction indicates a change in velocity, known as acceleration.
Why acceleration is tangent to the path?
Acceleration is tangent to the path because it is a measure of the rate of change of velocity. By being tangent to the path, acceleration describes how the direction or speed of an object is changing as it moves along a curved path. The tangential component of acceleration is responsible for changes in speed, while the normal component of acceleration is responsible for changes in direction.

What do you know about a ball when it is at the peak of the parabola of the path it follows?
The vertical component of its velocity is 0.

Tangential acceleration is the rate at which the tangential velocity of an object changes, causing the object to speed up or slow down in its circular motion.

Can a particle moving with uniform speed along a curved path have acceleration?
Yes, a particle moving with uniform speed along a curved path can have acceleration because acceleration is the rate of change of velocity, which includes changes in direction even if speed remains constant. In this case, the acceleration would be due to the change in velocity direction as the particle moves along the curved path.
What is instanteous velocity?
It is the exact velocity of an object at any point of its path. Remember that VELOCITY also has a direction component to it. Therefore at a constant SPEED an object following a curved path has a constantly changing Velocity. In other words the Vector that represents its Velocity has a changed value at every point.
Why is the motion of an athlete moving along the circular path an accelerated motion?
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.
Can the velocity of a car which is turning a curve be held constant?
The speed can be constant but the velocity can't, because the directionof motion ... which is a component of velocity ... is changing. Also the velocity of a moving body changes when its speed changes but remains moving towards the same direction ... :) :]
What is a acceleration in a circle?
Acceleration in a circle is the change in velocity of an object moving in a circular path. It can be either centripetal acceleration, which points towards the center of the circle and keeps the object on its path, or tangential acceleration, which changes the speed of the object along the circle.
