Circular Motion
Lesson duration is: 45 minItems in this lesson
Circular Motion
write 3 a real life examples for circular motion
MAIN IDEA
An object in circular motion has an acceleration toward the circle’s center due to an unbalanced force toward the circle’s center.
Essential Questions
Why is an object moving in a circle at a constant speed accelerating?
How does centripetal acceleration depend upon the object’s speed and the radius of the circle?
What causes centripetal acceleration?

what is the difference between centripetal acceleration and tangential acceleration?
What is centripetal acceleration?
Acceleration towards the center of circular path
Acceleration in a random direction
Acceleration away from the center
Constant speed in a straight line
What provides centripetal force?
Air resistance
Friction, tension, or gravity
Magnetic force
Inertia
What is the formula for centripetal acceleration?
a = mv
a = v²/r
a = r/v
a = vt
Which object experiences centripetal force?
A stationary object
An object moving in a straight line
A free-falling object
A car turning on a curve
Which factor increases centripetal force?
Increasing speed
Decreasing friction
Increasing mass of the object
Decreasing radius
A small plane makes a complete circle with a radius of 3282 m in 2.0 min. What is the centripetal acceleration of the plane?
A string can withstand a force of 135 N before breaking. A 2.0 kg mass is tied to the string and whirled in a horizontal circle with a radius of 1.10 m. What is the maximum speed that the mass can be whirled at before the string breaks?
