Essential Question: In what ways can an Object’s motion be changed? A police officer is called to the scene of a car accident. In his accident report he sketches the
scene and describes it. According to his description the car went off of the road and hit a tree
right after a bend. The driver claimed that a second car ran him off the road by hitting him from
behind. Using his observations and his knowledge of physics, the police officer determined that
the driver was not telling the truth.

Explain how the police officer determined that the car was not run off the road by a second car
that came from behind. In the figure above label the forces that must have acted on the car to
have it follow the path indicated with the arrow on the sketch of the scene.
In your written response, be sure to include:
1. the forces that must have acted on the car to have it follow the path indicated with the
arrow on the sketch of the scene.
2. how forces affected the motion of the car.

behind. In the figure above label the forces that would have acted on the car if it were hit from
behind.
