Is constant speed current velocity?
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
Is it possible to run round an oval running track at constant velocity?
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made. Again, note that speed can stay the same, but velocity has a direction vector associated with it that cannot be ignored.
What is an example of constant speed with changing velocity?
Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.
Is it possible for a body to have average speed but zero average velocity give reason and example?
Yes it is possible. If a body goes round a circular path then distance covered by one full rotation will be 2 pi r But the total displacement is 0. Hence the average speed exists but average velocity does not exist.
How does the tangential velocity of a planet relate to it orbiting around the sun?
The tangential velocity is equal to the circumference of the orbit divided by the time taken to go round once. For the Earth that is 2pi time 149.6 million kilometres divided by 365.25 days, which comes to 2.57 million km per day or 30 km/sec.
What is the maximum speed with which a 1200- car can round a turn of radius 72 on a flat road if the coefficient of static friction between tires and road is 0.65?
7
What is the maximum speed with which a 2500 kg car can round a turn of radius 60 m on a level road if the coefficient of static friction between tire and road is 7?
Really? A coefficient of friction of 7? Unheard of. Probably 0.7 Use F = mv^2 / r where F will be the centripetal force as well as the frictional force, (mu)mg. Solve for v.
When an object rolls over a surface the kind of friction that occurs is called round friction.?
it is called rolling friction
What is the lowest velocity?
Lowest velocity round such as a 30.06 barrel has a longer barrel life.
If the correlation coefficient r is equal to 0.35 find the coefficient of nondetermination?
The coefficient of nondetermination is found by 1.00-r squared so 1.00-0.35X0.35 1.00-0.1225 0.8772 round it to 0.88
When an object rolls over a surface the kind of friction that occurred is called round friction True or false?
false it is rolling friction

You are standing on a merry-go-round that is in motion what forces is keeping you from flying off?
Friction. Friction is a resistance to motion.
Is a present between the surface of round object and surface where its move?
Friction
Is a .30-30 round larger than a .30-06 round?
they have the same diameter but the .30-06 has a higher velocity.
What is the difference between sliding and rolling and kinetic and static friction?
Sliding friction is the friction between the body and the surface on which the body is sliding. Static friction however, is the friction when the body isn't moving when you aply force to it. The force of static friction is the same as the force you are pushing the body UNTIL it moves!..It's a fact that the static friction coefficient is a bit bigger than the sliding friction coefficient.
Is constant speed current velocity?
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
