Describe a situation in which you can accelerate even though your speed doesn'y change?
If you drive a car around in a circle your velocity is constantly changing (ie you are accelerating) but your speed could be constant. Velocity is speed with direction, so your speed could be a steady 10 metres per second but your velocity (ie direction) changes back and forward as you go around the circle. Acceleration with constant speed.
What happens to an object when it reaches terminal velocity?
It cannot go any faster. It's acceleration drops to 0 and the velocity stays constant.
Can you go around a curve with zero acceleration?
No, you can't do that. Any change of direction is an acceleration.
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.
Is the velocity constant for an object in uniform circular motion?
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
When you go around a curve is your velocity changing?
Yes; although speed ( a scalar quantity) may be constant the velocity ( a vector with quantity and direction) is changing because the direction is changing

Can uniform velocity appear in circular motion?
No.. this is impossible. Velocity must have a constant direction and speed to remain constant, it may have a constant speed, but the direction in a circle constantly changes. If it suddenly were to have constant direction, then the motion would go off on a tangent.. making it linear motion, not circular. In circular motion, velocity constantly changes. Always.
Can you accelerate if your speed is constant?
If you're travelling at a constant speed then you don't go any faster or slower.Acceleration, however, is change in velocity, and velocity is speed in a given direction. You can travel at a constant speed but be changing direction, (such as making a turn), and thus be accelerating.
What is a curve in track?
A curve in a track in the sides of the track in which there is a slight curve. Following this is the straighaway. Often, you will see runners curve their bodies as they go around this turn.
Why are you accelerating when you go around a corner at a constant speed?
Acceleration is any change in velocity. It could be a change in speed or direction. Technically, even slowing down is acceleration.
What is an velocity?
Velocity is the measure of increasing and decreasing speed. For example... on a velocity graph, if the object being measured is gradually getting faster the line will go up. If it is getting slower, it will go down, if it is staying at a constant speed, the line will be straight
Does a bicycle have to feel a force in the direction of its motion to go around a curve?
no
Do both terrestrial and jovian planets have orbital velocity?
Everything that has an orbit has an orbital velocity. Velocity=speed. It just means the speed they go around the sun.
Can you go around a curve with zero acceleration?
No, you can't do that. Any change of direction is an acceleration.
