Get Fan Cart Physics Gizmo Answer Key

Newton's second law describes the relationship among an object's mass, an object's acceleration, and the net force on an object. The acceleration is equal to the net force divided by the mass. If the net force acting on an object doubles, its acceleration is doubled.

Draw conclusions : Newton's first law states that an object in motion will travel at a constant velocity unless acted upon by an unbalanced force. How do these experiments show this? The experiments show Newton's first law because, when both fans are turned on by both ends, the force is balanced out and constant.

In blowing the air to the left, the fan exerts a leftward force on the air, which must in turn exert an equal rightward force on the fan. Since the fan is rigidly mounted to the cart, this rightward force on the fan accelerates the cart to the right.

If the mass is doubled, then acceleration will be halved. If both the net force and the mass are doubled, the acceleration will be unchanged.

with this, we can infer that the force and acceleration are directly proportional. Thus, when the force is doubled, the acceleration will simply be doubled.

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased.

When the force applied to the car is doubled, the acceleration of the car will also double. This is because force and acceleration are directly proportional to each other.

Final answer: A stronger fan on a fan cart would significantly alter the cart's motion by increasing its acceleration when speeding up and increasing its rate of deceleration when slowing down.
