A cyclist goes around a level circular track at constant speed. Is the cyclist's acceleration zero because her speed is constant?
No. The cyclist is moving at a constant speed, but her velocity is changing. Remember that velocity is speed with a direction vector associated with it. As speed is constant, only direction is changing. But a change in direction is a change in velocity (even if speed is constant), and this requires acceleration in that direction to accomplish the change in direction. You're on the right track, but just recall that acceleration is tied to velocity and not just speed. And note that velocity can change all the time without speed changing. Acceleration must cause the change in velocity. Consider that objects in orbit around the earth move at a pretty constant speed, but accelerate toward the earth all the time. Their speed coupled with their acceleration toward earth cause them to move in an arc - which is their orbital path.
Does acceleration change when a cyclist is moving at a constant speed around a corner?
No, acceleration is a change in velocity. When a cyclist is moving at a constant speed around a corner, the direction of their velocity changes but not its magnitude, so there is no acceleration in the direction of motion. There may be a centripetal acceleration towards the center of the curve to keep the cyclist moving in a circular path.
What describes the velocity of a cyclist?
The velocity of a cyclist is the rate at which the cyclist is moving in a specific direction, often measured in units such as meters per second or miles per hour. It indicates both speed and direction of motion.
What is the force that stops a cyclist from skidding away?
Friction between the tires and the road surface prevents the cyclist from skidding away. This friction allows the tires to grip the road and provides the necessary traction for the cyclist to maintain control while braking or turning.

It is often stated that many forms of transport transform chemical energy into kinetic energy Explain why a cyclist travelling at constant speed is not making this transformation?
Actually, a cyclist is. The chemical energy from the food that the cyclist ate is being changed into the kinetic energy on the bicycle. Even if the cyclist is traveling at a constant speed, there is some degree of resistance that must be overcome in order to maintain the constant speed.
Does acceleration change when a cyclist is moving at a constant speed around a corner?
No, acceleration is a change in velocity. When a cyclist is moving at a constant speed around a corner, the direction of their velocity changes but not its magnitude, so there is no acceleration in the direction of motion.

When does a cyclist appear to be stationary with respect to another moving cyclist?
A cyclist appears to be stationary with respect to another moving cyclist when they are both moving at the same speed and direction. This occurs when they maintain a consistent distance and speed relative to each other.
What describes the velocity of a cyclist?
The velocity of a cyclist is the rate at which the cyclist is moving in a specific direction, often measured in units such as meters per second or miles per hour. It indicates both speed and direction of motion.
What is the recommended distance that a driver should maintain from a cyclist on the road?
The recommended distance that a driver should maintain from a cyclist on the road is at least 3 feet.
What would be the problem if dynamos are the only way to provide electricity in bicycle lamps?
The problem is that your light would go out if you were not moving. Batteries allow the light to remain on even when you are not moving and turning the dynamo.
What is a cyclist doing when he is Honking?
Standing up, pedalling hard. Tilting the bike from side to side while pulling on the handlebar. It's a way to get the whole body and not just the legs into powering the bike frward.
What is the minimum required clearance a motorist must maintain form a cyclist?
You must give the cyclist 3 ft of clearance between your car and the bicycle.
What is the maximum required clearance a motorist must maintain from a cyclist?
There is no maximum required clearance
What is the force that stops a cyclist from skidding away?
Friction between the tires and the road surface prevents the cyclist from skidding away. This friction allows the tires to grip the road and provides the necessary traction for the cyclist to maintain control while braking or turning.
