Push harder and an object speeds up more. If the object is heavier, it speeds up less with the same push.
Which will speed up more with the same push: a loaded shopping cart or an empty one?
Know any two variables to find the third.
Compute push required to speed up a trolley.
Estimate mass when force and acceleration are known.
Predict how fast a scooter speeds up under a given force.
Relationship examples—see how force or mass changes acceleration.
Mass same ⇒ acceleration doubles.
Force same ⇒ acceleration halves.
Acceleration is zero; speed and direction stay same.
Remember: \(a = \frac{F}{m}\) — direct with force, inverse with mass.
A 4 kg cart is pushed with 12 N. Using \(F = m a\), what is its acceleration?
Rearrange \(a = \frac{F}{m}\).
Great job. You applied the second law correctly.
Check the formula \(a = \frac{F}{m}\) and try again.
More applied force gives greater acceleration.
A larger mass accelerates less under the same force.
Newton summed it up: \(F = m \times a\).
Acceleration grows with force and shrinks with mass.
