Recognize that forces can change an objects speed or direction?
all external forces can change the velocity of a body e.g.(gravity,friction etc.)
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.
What is a objects speed and direction?
Its called VELOCITY.
What is the difference between a objects speed and an objects velocity?
Velocity also includes direction.
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.
How do you measure an objects speed and direction?
Velocity
What describes an objects speed and its direction?
Velocity.
Is velocity an objects speed and direction of motion?
Velocity is an objects speed in a given direction e.g. a runner having run round a circular track of 400m in circumference has 0 velocity.
What is the difference of an objects speed and an objects volocity?
when you know both speed and direction of an objects motion you know the velocity of an object.
How does an unbalanced force affect a moving object at a constant velocity?
If the group of forces on an object is unbalanced, then the object can't have constant velocity. Its speed or the direction of its motion must change.
Consists of an objects speed and direction?
angular velocity
How do the mass and speed of an objects affect the kinetic energy?
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
