When a card supporting a coin on a glass tumbler is suddenly flicked it is observed that the card flies off but the coin falls in the tumbler ,this is because the coin ends to maintain its state of rest ,

Which type of motion is this?

• 10m/s²

• 20m/s²

• 0.10m/s²

State the law of linear momentum

• States that for every action there is an equal and opposite reaction force

• Stated as the product of force acting on a body

• States that for a system of colliding bodies , the total linear momentum is a constant, provided no external forces are acting

• Stated as the measurements for physical quantities that are obtained for combining base units
