Physics Kinematics
Motion described as change in position with respect to a frame of reference; can be linear or angular.
What is kinematics?
In projectile motion (neglecting air resistance), what is true about horizontal and vertical motions after release?
What is vertical motion is independent of horizontal motion?
Angular displacement unit used often in physics besides degrees and revolutions.
What is radians?
Kinetics studies these; examples in running include forces between feet and ground and muscle contraction.
What are forces (causes of motion)?
Overall motion used in a movement, described by linear or angular motion of body segments.
What is range of motion?
Quantity defined by magnitude only (examples: temperature, mass, distance).
For a ball tossed up at +10 m/s and caught at same height, what is the velocity upon return (neglecting air resistance)?
What is -10 m/s?
Angular analogue of linear velocity
What is Angular Velocity?
Newton-based principle stating unbalanced forces act on bodies when we create or modify movement
What is the Force–Motion Principle?
Ability to control your body’s position relative to its base of support.
What is balance?
Quantity that has both magnitude and direction; examples include velocity and displacement.
What is a Vector?
Determining a single vector from 2 or more is...
What is Vector Composition?
Name the angular quantity analogous to linear acceleration.
What is angular acceleration?
Principle that heavier objects resist changes in motion more than lighter ones.
What is Inertia?
Principle describing the optimal release angle to achieve a specific goal
What is Optimal Projection?
The rate of change of displacement with respect to time; units like m/s and includes a direction.
What is velocity?
The vector equivalent of speed is...
What is Velocity?
Angle measured relative to an unmoving earth frame: what is this called?
What is an Absolute angle?
Principle describing transformation of forces between linked body segments.
What is segmental Interaction?
A change in position with respect to some frame of reference
What is Motion?
The second derivative of displacement or the rate of change of velocity; units m/s^2 and caused by unbalanced forces.
What is acceleration?
What is the scalar equivalent to weight?
What is Mass?
Angle between two angles that can move
What is a Relative angle?
Principle stating the longer a force is applied, the greater the impulse and resulting motion
What is the Force-Time Principle?
Description of angular motion or rotation
What is angular kinematics?
