Drag each statement into the correct bin based on whether it describes motion that involves acceleration or motion at constant velocity.
Acceleration:
- A ball is in freefall after being dropped from a high window.
- A planet is orbiting the Sun in an elliptical orbit.
- A car is holding a steady speed around a curve.
- A car is speeding up after being stopped.
- A planet is orbiting the Sun in a circular orbit.
- A car is slowing down for a stop sign.
Constant Velocity:
- A spaceship is coasting without engine power in deep space.
- A car is driving 100 km/hr on a straight road.
- An elevator is going upward at constant speed.
Note: For the motions that are on Earth (e.g., car, ball, elevator), ignore any effects of Earth's rotation or orbit.
