What is the speed of a swallow caring a coconut?
African or European swallow?
What does distance times velocity or time equal?
it = speed over time
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.
What are the similarities between speed and acceleration?
The two words are synonyms. However, in physics there is a more precise definition, which is a change in an object's position in a specified direction with time. So in everyday language we could say the speed of the car is 60 miles per hour, but in physics you'd say its velocity is 60 miles per hour North/South/East/West.
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).
