SP2a
Construct an explanation based on evidence using Newton’s Laws of how forces affect the acceleration of a body. • Explain and predict the motion of a body in absence of a force and when forces are applied using Newton’s 1st Law (principle of inertia). • Calculate the acceleration for an object using Newton’s 2nd Law, including situations where multiple forces act together. • Identify the pair of equal and opposite forces between two interacting bodies and relate their magnitudes and directions using Newton’s 3rd Law.
