motion of an object turning around an axis outside the object (turns about external axis)

Revolution

the spinning motion that takes pace when an object about an axis located within the object (turns about internal axis)

Rotiation

the number of rotation or revolutions er unit of time; often measure in rotations or revolutions per second or per minute

Rotational speed

both the orbiting cannon ball and the moon have a component of velocity parallel to Earth’s surface. Measures circular motion around the earth

Tangential speed

An object in motion will remain in motion in a straight line at a constant speed unless acted upon by an unbalanced force

Newtons First Law

A center directed force that causes an object to move in a curved (sometimes circular) path

Centripetal Force

An apparent outward force on a rotation or revolving body. It is fictitious in the sense that it is not part of an interaction but is to the tendency of a moving body to move in a straight line path

Centrifugal Force

Accelerating object are ________.

Changing velocity

A car that is moving in a circle at a constant speed is_________________________________.

Accelerating since there is a change in velocity

An object hat is moving in a circle at a constant speed has a velocity vector that is directed____________ and an acceleration vector that is directed________________.

Tangent to the circle, inwards

An object that is moving in uniform circular motion will definitely have a large acceleration if it is ____________.

Turning at a rapid rate

THe net force acting upon an object is ___________ as the direction of the object’s acceleration

In the same direction

A quantity that is fully described by magnitude alone is a ________________.

Scalar

A quantity that is fully described by both magnitude and direction is a _____________ quantity

Vector

Speed is a__________ quantity.

Scalar

Velocity is a __________ quantity.

Vector

An object which moves uniformly in a circle can have a constant____________ but a chaning

Speed/Velocity

The direction of a velocity vector is always_________.

In the same direction as the object is moving

For an object moving in uniform circular motion, the velocity vector is directed

In the direction of the tangent line drawn to the circle at the objects location
