Answer 1

Here are the answers to the questions based on the provided information:

Question 1: A) What is the measure of the amount of matter in an object?

• Answer: mass

Question 2: A) How much force in Newtons is required to accelerate a 5 kg bowling ball at 2 m/s²?

• To find the force, you can use Newton's second law: \( F = m \times a \).
• \( F = 5 , \text{kg} \times 2 , \text{m/s}^2 = 10 , \text{N} \)
• Answer: 10 N

Question 3: A) Which statement correctly applies to a car that changes its velocity over a period of time?

• If a car changes its velocity, there must be a net force acting on it.
• Answer: A nonzero net force is acting on it.

Question 4: A) In each of three trials of an investigation, a single force is applied to a mobile. Each time, the mobile acquires a different acceleration. Which phrase best describes a graph that would represent the relationship shown in the table?

• The data indicates that as force increases, acceleration also increases, suggesting a direct relationship.
• Answer: an upward-sloping line drawn on a graph with acceleration shown on the y-axis and force shown on the x-axis

Question 5: A) Which statement describes the motion of an object when the net force is zero?

• If the net force is zero, the object can either be at rest or moving at a constant velocity (not changing speed).
• Answer: The object is at rest.
