A passenger moving forward in their seat when a car suddenly stops. A ball thrown straight up into the air coming back down. 4 / 10 What role does friction play in Newton's First Law? It is the force that keeps objects in motion. It is the force that changes an object's direction. It is an external force that can stop a moving object. It has no effect on motion. 5 / 10 Which statement is true regarding an object at rest according to Newton's First Law? It will stay at rest unless an unbalanced force acts upon it. It will eventually start moving on its own. It will stay at rest only if the surface is frictionless. It will start moving if it has mass. 6 / 10 If no external force acts on a moving object, what will happen to the object? It will eventually stop. It will change direction. It will continue moving at the same speed in the same direction. It will accelerate. 7 / 10 Which of the following is an example of Newton's First Law? A car accelerating when the gas pedal is pressed. A book remaining at rest on a table. A ball rolling down a hill. A rocket launching into space. 8 / 10 What is inertia?
