Questions & Step-by-Step Solutions
What is the acceleration of a rolling object down an incline if the incline angle is θ?
Step 1: Understand that 'g' represents the acceleration due to gravity, which is approximately 9.81 m/s².
Step 2: Identify the angle of the incline, which is given as θ.
Step 3: Recognize that when an object rolls down an incline, both its translational (straight-line) and rotational (spinning) motions need to be considered.
Step 4: The force acting on the object due to gravity can be broken down into two components: one parallel to the incline (which causes acceleration) and one perpendicular to the incline (which does not cause acceleration).
Step 5: The component of gravitational force acting down the incline is calculated as g sin(θ).
Step 6: For a rolling object, this force causes both translational acceleration and rotational motion, which affects the overall acceleration.
Step 7: The formula for the acceleration of a rolling object down an incline is derived to be g sin(θ) divided by 2, which accounts for the rolling motion.
