Exploring Types of Forces in the Real World

This assignment will help you identify and explain how different types of forces—gravity, friction, magnetism, applied forces, and normal forces—act on objects in real-world situations. Read each question carefully and use what you have learned from the reading to answer. Be sure to answer the open response questions in complete sentences.

Which of the following is an example of a non-contact force?

Answer the following questions in complete sentences. Use examples from your own experiences or from the reading.

Describe a real-world situation where friction is helpful. Explain why friction is important in that situation.

Explain how gravity and normal force work together to keep a parked car in place on the ground.
