Speed is the distance traveled by an object where as, velocity is distance traveled by an object per unit time in a particular direction. 1 of 5 What is meant by 'momentum is conserved'? So long as no external forces are acting on the objects involved, the total momentum stays the same in explosions and collisions. 2 of 5 How do seat-belts protect us? They are designed to stretch in a collision. This increases the time taken for the body's momentum to reach zero, so reduces the forces on it. 3 of 5 - - 4 of 5 - - 5 of 5
