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.
A student riding her bicycle on a straight flat road covers one block every 7 seconds if each block is 100m long she is traveling at?
Constant speed and constant velocity
Can you accelerate and keep the same speed?
Acceleration means any change in either speed or direction of motion.If speed remains constant, there may still be acceleration present if thedirection of the motion is changing.If the rate at which speed and/or direction are changing remains constant,then the acceleration is constant
Does momentum have a direction?
Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.
What is required to change velocity of an object?
In order for an object to travel with constant velocity the sum of forces acting on it must be 0 N. According, to Newton's second law, ΣF = ma where ΣF is the sum of forces m is mass a is acceleration If the acceleration is not 0, then the object is not traveling at a constant velocity. In order for a to equal 0, the sum of forces must be 0 because by solving Newton's second law for a, we get a=ΣF/m If ΣF is not 0, then that equation will never allow a to equal 0 and the object will b accelerating. Therefore, the sum of forces must equal 0 for an object to travel with constant velocity.
Are you accelerating if you are traveling in a constant direction with constant speed and explain?
No, you are not accelerating if you are traveling in a constant direction with a constant speed. Acceleration is the rate of change of velocity, so if your velocity remains constant, there is no acceleration.
Can an object traveling at constant velocity have acceleration?
No, if an object is traveling at a constant velocity, it means that its speed and direction are not changing. Acceleration is the rate at which velocity changes over time, so an object with constant velocity by definition cannot have acceleration.
Can a bus change the direction of its velocity when traveling with a constant acceleration?
Yes, a bus can change the direction of its velocity while traveling with a constant acceleration. This change in velocity is due to the vector nature of acceleration, which can cause the bus to turn or change its direction even if its speed remains constant.
Can a bus change direction of its velocity when traveling with constant acceleration?
Yes, a bus can change the direction of its velocity when traveling with constant acceleration. This change in velocity can occur when the bus is accelerating in the opposite direction to its initial velocity. The bus will slow down, stop, and then start moving in the opposite direction.
Does a car traveling along a curved path at constant speed have a constant momentum?
Yes, a car traveling along a curved path at constant speed does not have constant velocity since velocity is a vector quantity that includes direction. However, the magnitude of the car's momentum (which is the product of mass and velocity) can remain constant if there are no external forces acting on it.
Can you be accelerating if you are traveling at constant speed?
No, if you are traveling at a constant speed, you are not accelerating. Acceleration refers to a change in speed or direction.
If you are traveling around a curve at a constant speed of 30 km is the veiocity change?
Yes, the velocity is changing. Velocity is a quantity composed of the speed and the direction of motion. Constant velocity means: Constant speed, in a straight line. If the direction is changing, then the velocity is changing, even if the speed is constant.
Is it true or false that a body traveling at constant speed changes its direction without a change in its velocity?
False. A body traveling at constant speed does not change its velocity, which includes both speed and direction. Therefore, in order to change direction, the body would need to change its velocity, which also involves changing its speed.
Does the velocity of a car traveling at constant speed around a pole change?
No, the velocity of a car traveling at a constant speed around a pole remains the same as long as the speed is constant. Velocity is a vector quantity that includes both speed and direction. Since the car is moving in a circular path while maintaining a constant speed, its velocity is constant in magnitude but changes in direction.
Is a car on a circular track has also constant velocity?
No, a car on a circular track does not have constant velocity because velocity is a vector quantity and it includes both speed and direction. Since the car is constantly changing its direction while moving in a circle, its velocity is not constant even if its speed remains the same.
Does a car traveling 20 mph on a curved exit ramp have a constant velocity?
No it does not because once you change direction you do not have a constant speed.
If the speed of an does NOT change the object is traveling at a what?
It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.
