Physics Unit 3 PT Flashcards
an (object’s) Movement around an External Axis
Revolution
the Number of Complete Rotations Achieved By an Object in a given amount of Time; often measured in rpms
Rotational Speed
the Force Applied to a Rotating Object to Change its Rotational Inertia
Torque
During its flight, the path of the javelin follows a __________ Curve.
Parabolic
The Curve the javelin makes has both a __________ Vector and a __________ Vector.
Vertical , & horizontal
The Force that set the CD into a Spinning Motion Around its Axis is __________
Torque
an Objects Kinetic Energy, Plus its Potential Energy
Mechanical Energy
the Energy of an Object Based Upon its Position or its being Held Against a Force
Potential Energy
the Amount of Work Performed that can be Completed in a Given Time Period
Power
the Unit that Measures Power; it is Equivalent to One Joule of Work Performed in One Second
Watt
The SI Unit for Work is the __________.
Joule
The Joule is Equivalent to the Amount of Work it takes to Move One __________ One Meter.
Newton
In the English System, Work is Measured in __________.
Foot-Pounds
One __________ is Equal to 33,000 (ft-lb)/(min) or 550 ft-lb/s.
HorsePower
The statement “(A Ford Mustang) is Moving at 63 mph Northwest” describes the Mustang’s __________. speed of something in a given direction
Velocity
If the (Ford Mustang) accidentally Went Off the third floor of the parking garage, it would Accelerate towards the street due to the Force of __________.
Gravity
If the (Ford Mustang) were to veer off the road and hit a sign, it would do much damage because its Mass of 1533.142 kg (x) its Velocity of 110 kph Means it has a High __________. an objects movement determined by multiplying the object’s mass by its velocity
Momentum
If the Momentum of the (Ford Mustang) Changed, it would be Due to __________.
An Impulse
Since the (Ford Mustang’s) Velocity, Acceleration and Momentum all Involve Direction, these Quantities are __________ Quantities.
Vector
The Speed at which the (sticky note) Follows the Circumference in Rotation Around the tire’s Axis is the (sticky note’s) __________ Speed.
Rotational
The Speed with which the (sticky note) Would Have if it Became Unattached During the Tire’s Rotation is the (sticky note’s) __________.
Tangential Speed
D represents the __________ that Makes the (sticky note) try to Move Inward to the Tire Axis
Centripetal Force
The Tire and the Axle it is Attached to tend to Remain in Rotation due to __________.
Rotational Inertia
The Rate of the Tire’s Speed suddenly Increases. The (sticky note’s) Speed also Increases. Another way of saying this is that the (sticky note’s) __________ Increases.
Centripetal Acceleration
The Amount of Force needed to Move the (tire) 5 miles is Equal to the __________ required to Perform that task.
Work
the Amount of Work Done to Move the (tire) 5 miles in 5 minutes is Equal to the __________ necessary to perform that task.
Power
