F = m x a investigations — Homework
Use F = m x a. Rearrange when solving for mass or acceleration.
- 1.A 3 kg object accelerates at 5 m/s^2. Find the force.
- 2.A 20 N force acts on a 4 kg cart. Find the acceleration.
- 3.A 9 N force produces 3 m/s^2 of acceleration. Find the mass.
- 4.A 6 N force is applied to a 1 kg cart and then a 2 kg cart. Which accelerates faster, and what are the two accelerations?
- 5.Why does F = m x a mean a fully loaded truck needs a much bigger engine force than an empty one for the same acceleration?
