What type of graph represents acceleration for a block being pulled without friction?

• A. Constant acceleration
• B. Decreasing acceleration
• C. Zero acceleration
• D. Variable acceleration

Answer: (A)

The correct answer is a graph representing constant acceleration for a block being pulled without friction. In the absence of friction, the forces acting on the block are likely to be unopposed, assuming a constant force is applied. This consistent force results in a uniform acceleration according to Newton's second law of motion (F = ma), where force equals mass multiplied by acceleration. When a force is applied constantly over time without interruption or changes in magnitude, the acceleration will also remain constant. This means that if you were to plot acceleration against time, you would see a horizontal line at a value corresponding to that constant acceleration — indicating that the block consistently speeds up at that rate. This situation contrasts with other options. A graph depicting decreasing acceleration would suggest that the block is experiencing a reduction in its acceleration over time, which does not apply here since we know friction is not present to cause that effect. Zero acceleration would imply the block is not changing speed, indicative of no net force acting on it, which contradicts the premise of the block being pulled. Variable acceleration would reflect changing rates of acceleration, indicating that either the force applied is changing or there are external influences; however, the scenario provided specifies a simple case without friction, which maintains a constant force,
