Rotational Motion Flashcards
What is the part of the catapult that gives its projectile an initial velocity?
Lever arm
If you wanted a projectile to go very far, should it have a big, or a little initial horizontal velocity?
Big
Rotational motion
A special type of motion that turns
UNIFORM CIRCULAR MOTION
Motion of an object in a circle is at a constant speed
Tangental
Just touching the circle ONCE
Equation for speed:
Time
What is distance when you are going around a circle?
Circumference
What is time when you are going around a circle?
The time an object Takes to go around the circle ONE TIME. This is called a PERIOD –> T
Periods= seconds
Average speed(circular)
Circumference/time
What if your circle is bigger?
Speed increases.
Acceleration for uniform circular motion is always pointed ————————
Towards the center of the circle
