Ch 10
this is the change in position
what is displacement?
this measures the entire length of an object's path?
what is distance?
this is a vector (magnitude/direction).
what is velocity?
this is a scalar (no direction).
what is speed?
this is a way movement displays positive acceleration.
what is the body speeding up?
what is the body slowing down?
this measure the change in the distance over time.
what is speed?
what is velocity
this is the change in velocity divided by the change in time.
what is acceleration?
this is a body in free fall that is subject only to the forces of gravity and air resistance.
what is a projectile?
what is vertical component of a projectile?
this is influenced by the speed at which it moves.
what is the horizontal component of a projectile?
what is kinematics?
this is V2= V1+at
what is final velocity after acceleration?
this is d=V1t+1/2at^2
what is distance covered?
what is final velocity after a distance?
this is the role direction plays in distance and displacement.
what is it relates the final position to the initial position?
when acceleration is zero, velocity is.
what is constant?
when pv goes up, d goes
what is up?
this is the impact of trajectory.
what is the projectile angle or angle of projection?
vertical equals
gravity
horizontal equals
air resistance
vertical V is always
what is zero?
this is the variable of projectile motion that projectile angle affects.
what is the shape of the projectile's trajectory?
this is the units of linear speed.
what is m/s?
