What is natural movement in a gravitational field? - correct answerAll objects move in the direction of the g field on their own. Unnatural movement is against the field (when a force is exerted against the field). What is Displacement? - correct answerDisplacement is the change in location of an object. What is Velocity? - correct answerVelocity is the rate of change of displacement (x) v=x/t What is Acceleration? - correct answerAcceleration is the rate of change of velocity (v) a=v/t What determines direction generally when describing a moving object problem? - correct answerDirection is determined by the direction of the acceleration otherwise it can be decided arbitrarily Basic Kinematic Equations - correct answerΔv=v(f)-v(i) ā=(v(f)-v(i))/Δt āΔt=v(f)-v(i) V(f)^2=V(i)^2+2aΔx V(f)=V(i)+āΔt x=X(o
