Here are the answers to the questions on your worksheet.
1. $F = ma$ (or Force = mass $\times$ acceleration)
2. The diagram shows that when the foot kicks the ball forward (action), the ball pushes back against the foot with equal force (reaction). This is why you feel the impact on your foot when you kick something hard.
3. true
4. true
5. 27 newtons
*(Reasoning: Force = mass $\times$ acceleration. So, $3 \text{ kg} \times 9 \text{ m/s}^2 = 27 \text{ N}$.)*
6. mass
*(Reasoning: Inertia depends on how much stuff is in an object, which is its mass, not how fast it is going.)*
7. Inertia is the tendency of an object to resist a change in its motion. This means if an object is sitting still, it wants to stay still, and if it is moving, it wants to keep moving at the same speed and direction unless a force acts on it.
