Students were testing the effect of force on two different objects. Object 1 had a mass of 10 kg and Object 2 had a mass of 15 kg. Both objects were pushed with the same force. Which of the following statements accurately describe the motion of the objects?

Select TWO correct answers. 

• Both objects will move in the same direction at the same speed.

• Both objects will move in the same direction with Object 1 having a greater speed. 

• Object 2 will travel a farther distance with a lesser speed than Object 1. 

• Object 1 will travel a farther distance with a greater speed than Object 2.

According to Newton’s Third Law, what happens when a runner pushes back against the ground to propel themselves forward?

• The ground does not exert any force on the runner.

• The ground simultaneously exerts twice as much force on the runner.
