Question

Write a hypothesis about the effect of the angle of the track on the acceleration of the cart. Use the "if . . . then . . . because . . .” format and be sure to answer the lesson question: "How does an object's position and velocity change as the object accelerates?”

Answer 1

if the angle of the track increases, then the acceleration of the cart increases. This means that as the angle of the track becomes steeper or higher, the cart will experience a greater acceleration.

The "if...then...because" format is used to explain the cause-and-effect relationship between the variables being studied. In this case, the "if" part states the condition or variable that is being changed, which is the angle of the track. The "then" part states the effect or outcome that is expected to happen, which is the acceleration of the cart.

The "because" part provides the reasoning behind the hypothesis. It explains that a greater track angle increases the cart's velocity. This is because as the track becomes steeper, gravity pulls the cart more directly downward, resulting in a larger component of the force acting in the direction of motion. As a result, the cart accelerates more quickly.

Answer 2

Sample Response: If the angle of the track increases, then the acceleration of the cart increases because a greater track angle increases the cart's velocity.

Step-by-step explanation:

because.
