The stretch of the spring is a measure of the applied force.

Newton’s 1 st Law Inertia. Force Anything capable of changing an object’s state of motion Any push or pull Causes object to speed up, slow down, or change.

Dynamics: Newton’s Laws of Motion

Force. Something that changes the state of rest or the state of motion of an object. Can be a push or a pull Unit of measure Newtons N.

Question #1 A car is sitting in a parking lot at rest. What are the net forces on the car?

Question #2 John is driving along the highway at a speed of 60 mph. He then puts the car in cruise control so that he maintains that speed. What is the net force on the car?

Question #3 A cart is pushed to the right with a force of 5 Newtons. At the same time, someone is pulling the cart to the right with a force of 10 Newtons. What is the net force on the cart?

Question #4 A cart is pushed to the right with a force of 5 Newtons. At the same time, someone is pulling the cart to the right with a force of 10 Newtons. If the cart has a total mass of 4 kg, what is the cart’s acceleration (include direction)?

Question #5 A basket of apples is pulled to the right. The basket experiences a small friction force to the left. The pull force is larger than the friction force so the basket accelerates to the right. Using the equation F= M x A, explain what you could do to reduce the acceleration of the basket.

Question #6 A box pushed across the floor with a force of 8 Newtons experiences a friction force of 7 Newtons. What is the net force on the box?

Question #7 A box pushed across the floor with a force of 8 Newtons experiences a friction force of 9 Newtons. If the box has a total mass of 5 kg, what is the acceleration of the box?

Question #8 Is the box speeding up or slowing down? How do you know?
