Key Stage 4
*Decreasing [[speed]] - The [[magnitude]] of the [[velocity]] decreases, also known as [[deceleration]].
*Changing direction - The [[magnitude]] of the [[velocity]] remains constant (constant [[speed]]) but the [[object]] changes direction of travel.
: [[AccelerationNewton's First Law]] indicates that [[acceleration]] occurs due to [[Unbalanced Forces|unbalanced forces]] on an [[object]]:''An [[object]] in motion will tend to stay in motion and an [[object]] at rest will tend to stay at rest unless an [[Unbalanced Force|unbalanced force]] acts upon it.''
