3.1 motion errors

Stopping distance graph: What variables go on the y-axis and x-axis for d = vt + (v²)/(2a)?

y-axis: d/v | x-axis: v

Stopping distance graph (d/v vs v): What do the gradient (m) and y-intercept (c) represent?

Gradient (m) = 1/(2a) (so a = 1/2m))

y-intercept (c) = reaction time (t)

How can you measure force applied with a spring practical

By using/ pulling with a newton meter

Combined spring mechanics: How do you find the effective spring constant (k_eff) for two springs in parallel vs in series?

Parallel: add them up (k + k = 2k) | Series: reciprocal sum (1/k total = 1/k1 + 1/k2)

On a speed-time graph, what shape represents a decreasing deceleration (decreasing force over time)?

A smooth curve starting at (0, U) with a continuously decreasing gradient ending at (2.0, 0)
