Papers 1 and 2

I can describe the effects of forces between bodies, such as changes in speed, shape or direction.
I can identify different types of force, such as gravitational or electrostatic forces.
I understand how vector quantities are different from scalar quantities.
I understand that force is a vector quantity.
I can calculate the resultant force of forces acting along a line.
I know that friction is a force that opposes motion.
I know and can use the relationship between unbalanced force, mass and acceleration: force = mass × acceleration, F = m × a
I know and can use the relationship between weight, mass and gravitational field strength: weight = mass × gravitational field strength, W = m × g
I know that the stopping distance of a vehicle is the sum of the thinking distance and the braking distance.
I can describe the factors that affect a vehicle's stopping distance, including speed, mass, road condition and reaction time.
I can describe the forces acting on falling objects (and explain why falling objects reach a terminal velocity).
Practical: I can investigate how the extension of helical springs, metal wires and rubber bands varies with the applied force.
I know that the initial linear region of a force-extension graph is linked to Hooke's law.
I can describe elastic behaviour as a material's ability to return to its original shape once the forces that deformed it have been removed.

I know and can use the relationship between momentum, mass and velocity: momentum = mass × velocity, p = m × v
I can use the idea of momentum to explain safety features.
I can use the conservation of momentum to calculate the mass, velocity or momentum of objects.
I can use the relationship between force, change in momentum and time taken: force = change in momentum / time taken, F = (mv − mu) / t
I can show that I understand Newton's third law.
I know and can use the relationship between the moment of a force and its perpendicular distance from the pivot: moment = force × perpendicular distance from the pivot
I know that the weight of a body acts through its centre of gravity.
I can use the principle of moments for a simple system of parallel forces acting in one plane.
I understand how the upward forces on a light beam supported at its ends change with the position of a heavy object placed on the beam.
