What else can I help you with?
How can you change only one component of the velocity without changing the speed?
You can change the direction of the velocity without changing the speed. This can be done by adding or subtracting velocity components in different directions, while maintaining the magnitude of the velocity vector.
Can a change in velocity always indicate a change in speed?
Velocity has direction as well as magnitude. Speed only has magnitude. So the velocity of something can change without its speed changing. This is what is happening when something is going in a circle.
When you change speed and direction you are changing what?
When you change speed and direction, you are changing your velocity. Velocity is a vector quantity that includes both speed and direction. So when you modify either speed, direction, or both, you are altering your velocity.
Describe a situation in which an object accelerates without changing speed?
Acceleration is the rate of change of velocity over time, so velocity must always be changing if the object is accelerating. HOWEVER, you said speed which means only magnitude, not direction. If you stay the same speed, but change direction then you are accelerating. Simple answer: when you are going the same speed in a circle - velocity changes, therefore acceleration changes.
Can a car move with changing velocity while maintaining constant speed?
No, if a car is changing velocity, it is not maintaining a constant speed. Velocity includes both the speed and direction of an object's motion, so any change in velocity would involve a change in speed, direction, or both.
Is changing direction really the same as changing speed?
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
How can you change only one component of the velocity without changing the speed?
You can change the direction of the velocity without changing the speed. This can be done by adding or subtracting velocity components in different directions, while maintaining the magnitude of the velocity vector.
Can the velocity of a body be constant still varying its speed?
Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.
Can a change in velocity always indicate a change in speed?
Velocity has direction as well as magnitude. Speed only has magnitude. So the velocity of something can change without its speed changing. This is what is happening when something is going in a circle.
When you change speed and direction you are changing what?
When you change speed and direction, you are changing your velocity. Velocity is a vector quantity that includes both speed and direction. So when you modify either speed, direction, or both, you are altering your velocity.
Why achanging velocity cannot maintaining constant speed?
Velocity is a vector quantity that includes both speed and direction. If the velocity is changing, it means either the speed, direction, or both are changing. Therefore, if the velocity is changing, the object cannot maintain a constant speed.

No, if a car is changing velocity, it is not maintaining a constant speed. Velocity includes both the speed and direction of an object's motion, so any change in velocity would involve a change in speed, direction, or both.
How do you accelerate without changing speed?
To accelerate without changing speed, you can change direction. Acceleration is the rate of change of velocity, which includes speed and direction. For example, a car moving at a constant speed on a curved path is constantly changing direction and therefore accelerating, even though its speed remains constant.
What control on a car can cause a change in velocity at constant speed?
The steering wheel can change the car's direction of motion, without changing speed.
Is it true or false that a body traveling at constant speed changes its direction without a change in its velocity?
False. A body traveling at constant speed does not change its velocity, which includes both speed and direction. Therefore, in order to change direction, the body would need to change its velocity, which also involves changing its speed.
Is a car moving around a curve without changing speed accelerating?
Yes. Even though its speed doesn't change, its velocity does change, therefore it is accelerating.
