• tension
• directed toward the center of the arena
• 9.8 N

Which of the following is the unit for centripetal force?

• J
• m/s²
• kg⋅m/s
• N

What is the relationship between centripetal force and the mass of an object?

• direct
• inverse
• exponential
• inverse squared

Which of the following increase the centripetal force?

• Increasing the radius
• Increasing the velocity
• Decreasing the mass
• Decreasing the acceleration

When an object is in circular motion it is constantly changing its velocity.

• True
• False

The centripetal force of satellites is similar to gravitational force because they are both a net force towards the center of earth.

• True
• False

If centripetal force stopped acting on all satellites they would continue traveling in space in a constant direction and constant speed.

• True
• False
