What happpens to a car moving at a constant speed as it turns a corner?

The car undergoes a change in velocity. It accelerates (and does so at a constant rate - if the rate of turn is constant) in the direction of the turn. The speed is constant, but the direction the car is going changes at each instant in time because it is turning. And because it is changing direction, that means its velocity is changing (because velocity is speed plus a direction vector).

What do you mean when we talk about a constant speed?
No. Circular motion can have constant speed but varying velocity. Constant speed means constant speed in any direction, like a car on cruise control turning a corner. Constant velocity means constant speed in a straight line. If the direction changes, that's considered a change in velocity.
Why does a car need force from its engine when moving at a constant speed?
If there be no force ie no deceleration then no need to apply any force to compensate such a deceleration. But deceleration is there due to frictional force between the tyre and the road. Hence to compensate this we have apply acceleration. So force is needed OK Physics laws State that an object in motion will remain in motion until acted upon by an outside force. The car moving at a constant speed is being acted upon by wind resistance, gravity, and friction. Therefore force is needed to retain the constant speed
What is the similarity between constant speed and acceleration?
If the speed is constant then equal distances are covered in equal intervals of time If acceleration is constant then equal change in velocity occurs in equal intervals of time.
What propels a photon of light thru space for billions of miles?
You don't need to "propel" something, once it is already moving. The natural tendency is for a moving object to continue moving. It requires a force to STOP a moving object, but not to keep it moving at a constant speed. Now, light behaves not just as a particle (photon) but also as a wave; but I believe that the general principle is still the same.
What is a synchronous motor?
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
Does acceleration change when a cyclist is moving at a constant speed around a corner?
Yes, because his/her direction is changing. If you are referring to the actual number (0 m/s2, because he/she is moving at a constant speed), no, that does not change.
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
Can you use average speed to calculate the speed of an object that is moving at a constant speed?
Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.
If a car moves at constant speed also moving at constant velocity give an example?
A car moving at constant speed in a straight line is also moving at constant velocity.
What is the difference between moving at a constant speed and not moving at all?
None, as "not moving at all" is just moving at a constant speed of zero. Special relativity shows that there is nothing unique or different about zero speed. It is just a value of constant speed.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
Determine if the momentum of an object moving in a circular path at constant speed is constant.?
determine if the momentum of an object moving in a circular path at constant speed is constant.
What does a flat line on a speed vs time graph mean?
it means the object is moving at a constant speed
What Is a constant speed?
When the speed of an object remains the same - it does not increase or decrease - we say it is moving at a constant speed.
What is constant speed Give an example?
if an object is moving without any net force or acceleration, it is moving at constant speed, or constant velocity. For example a satellite orbiting the earth is moving at constant speed, a car traveling at 60 mph, a wind of 20 mph. etc.
Does a car accelerate when it goes around a corner at a constant speed?
yes an acceleration is a change in speed and when you go around a corner you change your speed.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
