Forces are acting on it.
Forces are acting on it.
The combination of all forces acting on it is zero.
The combination of all forces acting on it is zero.
A nonzero net force is acting on it.
In each of three trials of an investigation, a single force is applied to a mobile. Each time, the mobile acquires a different acceleration. The table shows the relationship between the acceleration and the acting force.

Here are the answers to your questions:
1. **What is the measure of the amount of matter in an object?**
- **Response:** mass
2. **How much force in Newtons is required to accelerate a 5 kg bowling ball at 2 m/s²?**
- Using Newton's second law, \( F = m \times a \):
- \( F = 5 \, \text{kg} \times 2 \, \text{m/s}² = 10 \, \text{N} \)
- **Response:** 10 N
3. **Which statement correctly applies to a car that changes its velocity over a period of time?**
- **Response:** A nonzero net force is acting on it.
4. **Which phrase best describes a graph that would represent the relationship shown in the table?**
- Since the relationship shows that as the force increases, the acceleration also increases, it’s a direct relationship.
- **Response:** an upward-sloping line drawn on a graph with acceleration shown on the y-axis and force shown on the x-axis
5. **Which statement describes the motion of an object when the net force is zero?**
- The object would either remain at rest or move at a constant velocity.
- **Response:** The object is at rest (though it's worth noting that this statement doesn't account for constant motion; it could also be moving at a constant velocity).
