Question

which of the following toys are accelerating? select all that apply.
a wooden model airplane that is flying in small loops at a steady speed
a toy boat that is moving faster and faster as it plunges down a small waterfall
a frisbee that is slowing down after being thrown into the wind

Explanation:

Acceleration occurs when an object changes its speed (speeds up or slows down) or changes its direction of motion, even at constant speed.

1. The model airplane moves in loops, so its direction is constantly changing → it accelerates.
2. The toy boat is moving faster and faster, so its speed is increasing → it accelerates.
3. The Frisbee is slowing down, so its speed is decreasing → it accelerates.

Answer:

• a wooden model airplane that is flying in small loops at a steady speed
• a toy boat that is moving faster and faster as it plunges down a small waterfall
• a Frisbee that is slowing down after being thrown into the wind
