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?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
Can a bus change the direction of its velocity when traveling with a constant acceleration?
yes
Can a bus change direction of its velocity when traveling with constant acceleration?
Yes, if the acceleration is not colinear with the existing velocity.
Does a car traveling along a curved path at constant speed have a constant momentum?
No, the magnitude will be constant, but the direction of the momentum will change to reflect the direction of the velocity.
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.
Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
Is a car on a circular track has also constant velocity?
Yes, IF it maintains constant speed on the track. The academic definition of velocity is speed and the associated direction, a vector. A car traveling in a circle is constantly changing direction. However, most people, including physicists when they are not writing textbooks, treat velocity and speed as interchangable such that a car going a constant speed on a circular track would be considered to have a constant velocity even though the direction in which it is traveling is constantly changing.
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.
Does the velocity of a car traveling at constant speed around a pole change?
yes, 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).Read more: What_happpens_to_a_car_moving_at_a_constant_speed_as_it_turns_a_corner
Can you be accelerating if you are traveling at constant speed?
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
If a force is exerted on an object is it possible for that object to be moving with constant velocity?
Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
