Translational/Rotational Motion Flashcards
(34 cards)
When you ride a bike, it moves forward.
Translational Motion
When the wheels spin, they rotate around their axle.
Rotational Motion
Type of Motion: Translational
Moving in a straight line or along a path.
Type of Motion: Rotational
Spinning or turning around a point or axis.
Example of Translational Motion
A car driving on the road.
Example of Rotational Motion
A ceiling fan spinning.
Position of Translational Motion
How far you’ve moved (distance, like meters).
Position of Rotational Motion
How much you’ve turned.
Other term for Speed?
Velocity
Velocity of Translational Motion
How fast you’re moving (meters per second).
Velocity of Rotational Motion
How fast you’re spinning (degrees or radians per second).
Acceleration of Translational Motion
How quickly your speed changes.
Acceleration of Rotational Motion
How quickly your spinning speed changes.
It is how heavy something is. (Translational Motion)
Mass
How hard it is to spin something. (Rotational Motion)
Moment of Intertia
A push or pull that makes things move.
Force
A twist or turn that makes things spin.
Torque
KE for Translational Motion
KE = ½mv²
KE for Rotational Motion
KE = ½lw²
Cause of Motion: Translational
Net External Force
Cause of Motion: Rotational
Net External Torque
Key Similarities: Both type of motion have quantities:
Distance, velocity, acceleration, momentum, energy
Key Similarities: Both follow what in their respective forms?
Isaac Newton’s laws
Key Similarities: Both involve resistance to changes in motion (linear motion).
Inertia
