A student tests how mass affects acceleration by pushing different objects with a constant force. What data should they collect to support Newton’s Second Law?

• The shape and color of the objects

• The force applied and the acceleration of each object

• The number of times each object is pushed

• The time it takes for the objects to stop moving
