rocket booster initially applies 10,000 N of force to a 1,000.0 kg rocket causing it to accelerate at 10.0 m/s². Ten minutes later, the rocket booster is released and it falls through the atmosphere.

The mass of the rocket is now 760.0 kg and its acceleration is 7.0 m/s². How much force is now being applied to the rocket?

In a series of controlled experiments, students measure the different forces acting on a skateboarder as he travels down a hill. Then, they calculate the skateboarder’s acceleration for each of these forces. The students’ data table is shown. Based on the observations and the calculations made by the students, what is the estimated force applied to the skateboarder if the acceleration is .9 m/s²?

Record your answer. Be sure to use the correct place value.

A student is analyzing different conditions to understand how force and mass affect an object’s acceleration based on Newton’s second law of motion.

Which result BEST matches each condition?

• No change in acceleration

• Net force stays the same; mass increases

• Acceleration increases

• Net force and mass increase proportionally

• Acceleration decreases

• Net force increases; mass stays the same
