Check all that are true about the position time graph.

• The object is accelerating.

• The object is speeding up.

• The object is moving forward.

• The object is at rest.

An empty truck and a fully loaded truck are next to each other at a traffic light. When the light turns green, the lighter truck accelerates more easily than the heavy truck. Which best explains why this happens?

• Newton's first law

• Newton's second law

• Newton's third law

Which had the largest gravitational force acting upon it? (All objects are on the earth.)

• an adorable 5 kg dog

• a tall 115 kg person

• a 2540 kg elephant
