Circle the best answer, or write your answer on the line.
A cart runs around a circular track of radius 3 m at a steady 6 m/s. What is its acceleration toward the center, Ari?
A cart runs around a circular track of radius 0.5 m at a steady 5 m/s. What is its acceleration toward the center, Bo?
A cart runs around a circular track of radius 2 m at a steady 8 m/s. What is its acceleration toward the center, Esme?
In the diagram, which way does the ball's velocity point, Jun?
- Away from the center
- Along the circle, at right angles to the string
- Toward the center
In the diagram, which way does the net force on the ball point, Kira?
Use the picture in question 4.
- Toward the center
- Along the velocity
- Away from the center, flinging it out
In the diagram, what is the ball's acceleration toward the center, Luz?
Use the picture in question 4.
- 20 m/s²
- 3.2 m/s²
- 5 m/s²
A cart runs around a circular track, held in by an outer rail. What provides the force toward the center, Milo?
- Gravity pulling it down
- An outward push from its speed
- The rail's push on its wheels
A ball on a string whirls in a horizontal circle. What provides the force toward the center, Noah?
- An outward force from its motion
- Air pushing on the ball
- Tension in the string
A model satellite circles a planet. What provides the force toward the center, Pia?
- The planet's gravity
- The satellite's engines
- No force, since it is in space
A cart on a circular track reaches a gap in the outer rail. What does it do, Tala?
- Leaves in a straight line along its velocity
- Keeps curving around
- Stops at once
