An object's velocity is it's speed plus direction.
example: 55mph south
Hope this helps:)
What else can I help you with?
What is the term used to describe the rate of an objects movement?
velocity
How the velocity of an escalator that is going up different from the velocity of one that is going down at the same speed?
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
How do the velocities of unbalanced weights compared?
When dropped the mass of an object does not affect the rate at which it falls. The size and shape may affect the wind resistance which affects falling velocity but heavier objects will not fall faster than lighter objects with all other variables constant.
An objects resistance to change in motion?
Inertia. Inertia applies to both increases and decreases in velocity.
All objects have momentum?
To find the magnitude of momentum you use the formula: p=mv So, if an object has a mass (and if it exists then it would), and if it is moving (has a velocity), then yes, it has momentum.
How can one determine the relative velocity between two objects?
To determine the relative velocity between two objects, you can subtract the velocity of one object from the velocity of the other object. This will give you the relative velocity between the two objects.
Is it possible for an objects velocity to be perpendicular to the objects acceleration?
no
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
What resist change in velocity?
Objects with greater mass resist changes in velocity more than light objects. Additionally, objects with higher inertia or momentum also resist changes in velocity. Friction and air resistance can also act to resist changes in velocity.
Which term can be described both the speed and the direction of an objects motion?
VELOCITY
2 objects with same velocity have same momentum if they have the same?
mass. Momentum is the product of an object's mass and its velocity, so if two objects have the same velocity and mass, then their momentum will be the same.
What is the difference an objects speed and an objects velocity?
Speed only tells how fast something is going, while velocity tells speed and direction.
Is an objects momentum directly proportional to an objects velocity?
Yes, an object's momentum is directly proportional to its velocity. Momentum is defined as the product of an object's mass and velocity, so as velocity increases, momentum increases proportionally.
Science of describing the motion of objects?
velocity
When do you know an objects velocity?
When you have calculated or measured it.
How do you measure an objects speed and direction?
Velocity
What is the property of an objects mass and velocity?
An object's mass and its velocity define the object's MOMENTUM.
