Angles in the Outfield
The unit of measure for angles that is equal to 57.3 degrees.
What is a radian?
These are the rules we need to follow to translate angular kinematics to linear values.
1. Angle must be in radians
2. Linear units must match radius
A force applied to an object that causes displacement
The capacity or ability to do work.
What is energy?
Another way to say 4 revolutions.
8π radians
This is the acceleration directed towards the center of curvature.
What is radial acceleration.
Work applied for a short period of time.
What is power
The energy of motion.
The lower-case omega represents this angular kinematic values.
What is angular velocity?
This is the acceleration that represents the change in linear speed of an object traveling along a curved path.
What is tangential acceleration?
Unit to measure work.
What is a Joule?
The energy of position.
What is potential energy?
If you complete 1.6 revolutions of a spin, how many radians did you spin?
10.05 radians
A bike tire spins at a rate of 72 RPM, what is this value in radians/second?
7.54 radians/second
You exert a force of 13 N on a table to slide it across the room. If you are pushing at an angle of 43 degrees from horizontal and you moved the table 7 meters, how much work did you do?
66.55 Joules
In order to have kinetic energy, objects have to be in this state of motion.
What is a free fall?
A gymnast completed three backflips. Calculate how many degrees she rotated.
1080 degrees
If your bike tire travels 7.54 radians/second and has a diameter of 24 inches, how far did the outside of your tire travel in 45 seconds?
4071.6 inches
You are pulling a sled at the gym. You exert a force of 19 N at an angle of 48 degrees from horizontal. If you pull the sled a total of 100 yards in 23 seconds, how much power did you exert?
55.28 Watts
Solve for the velocity of a 15 kg object if it falls from a height of 2.3 m right before it hits the ground.
6.72 m/s
