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 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 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.
Real life example of second law of motion?
Constant velocity is the Newton's first law. A real life example is Sunlight, an example of constant velocity, light traveling at the constant speed of light.. On earth, an ice skater gliding or a hockey puck sliding on ice is a close example of nearly constant velocity. A stable oil drilling platform is close to zero constant velocity.

0.32 in. H20 per 100 ft.

A merry-go-round horse moves at a constant speed but at a changing?
. . . velocity, because one of the components of velocityis the direction of the speed.
What is the formula for acceleration?
a=dv/dt. By definition, acceleration is the rate of change of velocity. In mathematical notation, it is given as the formula stated above. Two special cases: 1. When acceleration is constant: The rate of change is a constant. Therefore, it can be calculated by: a=(vf - vi) / t where a is acceleration vf is final velocity vi is initial velocity and t is time taken 2. When velocity is constant: Velocity is not changing. The rate of change of velocity is zero. Acceleration has to be zero. * * * * * Note that velocity and acceleration are both VECTORS. Therefore, an object going round in a circle, at CONSTANT speed, has velocity and acceleration that are changing all the time - because the direction of motion is changing.
Is Accelerated is related to the statement Circular motion with uniform speed?
yes.acceleration means change of velocity and not speed to be more precise.in a circular motion with constant speed the particle or the object constantly changes its direction.the direction of velocity is directed along the direction of the tangent at that point.although speed remains constant the velocity changes infinite number of times.so the particle is said to be accelerating.there is always instantaenous acceleration.but the average acceleration becomes zero after every round because velocity becomes the same after every round.
Why is circular motion with constant speed called accelerated motion?
Acceleration is defined as change in velocity. Velocity is speed and direction. So when you're going round in a circle (circular motion), you're changing direction constantly, therefore changing velocity and therefore accelerating.
What is the lowest velocity?
Lowest velocity round such as a 30.06 barrel has a longer barrel life.
Acceleration is an increase of speed during a given interval of time?
No. It is the change in velocity (not speed) during a given interval of time. It can be an increase or a decrease although a decrease is also called a deceleration.The distinction between velocity and speed can best be illustrated by an object going round in a circle at a constant speed. It is changing direction all the time so that its velocity is constantly changing. It is constantly accelerating even though it is travelling at constant speed.
Running on a round track can you pass someone who is walking can you pass them every other lap?
Depending on the rate of speed, it is quite possible to do this.
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.
What is the correct idiom for the running round and round?
the runaround
Can a particle with zero acceleration spead up?
When it has zero acceleration, it is moving at a constant velocity. If you change that velocity then it is accelerating. Remember velocity is a constant speed in a given direction. If the direction changes, then its velocity is changing hence it is accelerating. That's why if you go round in a circle , e.g. a fairground ride, your velocity is changing, hence you are accelerating, and so feel as though you are going to be thrown outwards. Remember Sir Isaac Newton's three laws of Universal Dynamics. A body/mass will remain stationary or in uniform motion, unless acted upon by a force. Force is directly proportional to body/mass and acceleration. To every force there is an equal and opposite force.
