Question

A group of students conduct an experiment to study Newton’s second law of motion. They applied a force to a toy car and measure its acceleration. The table shows the results.

The table shows the relationship between the applied force and acceleration of a toy car.
Force (N) Acceleration (m/s²)
2.0 5.0
3.0 7.5
6.0 15.0
If the students graph the data points, which conclusion will they be able to make?

(1 point)
Responses

The data points will fall along a line. This shows that as the force increases, the acceleration increases.

The data points will fall along a line. This shows that as the force increases, the acceleration decreases.

The data points will not fall along a line. This shows that as the force increases, the acceleration increases.
The data points will not fall along a line. This shows that as the force increases, the acceleration increases.

The data points will not fall along a line. This shows that as the force increases, the acceleration decreases.

Answer 1

The first response. The points lie on a straight line, showing acceleration increases as force increases (directly proportional). (Here F/a = 0.4 kg, so m = 0.4 kg.)
