Further motion concepts

• Momenttum depends on the mass of an object and its velocity
• momentum = mass x velocity
• Momentum is a vector, which means it is important to consider the size and direction of the momentum in calculations
• The law of conservation momentum states that the total momentum before and after an interaction are equal, provided that no external forces are acting on the objects
• Conservation of momentum can also be applied to situations involving explosions where one stationary object explodes into two parts
• x represents displacement. This is the distance the object travels in a certain direction. it is measured in m
• u and v are both measured in m/s as they both represent velocity; u is the initial velocity and v is the final velocity
• a is the acceleration
• t represents the time taken
• The turning effect if a force us known as its moment
• The principle of moments states that for a body in equilibrium, the sum of the clockwise moments = the sum of the anticlockwise moments about the same point
