AP Physics - Unit 3

Front

What happens to your mass if Earth's mass is cut in half?

Back

Nothing, mass is not affected by gravitational force.

Front

What is the formula for centripetal force?

Back

F_c = (m * v^2) / r, where F_c is centripetal force, m is mass, v is tangential velocity, and r is radius.

Front

Calculate the tangential velocity if the centripetal force is 150 N and mass is 3 kg in a 2 m radius circle.

Back

10 m/s

Front

What is the formula to calculate acceleration in circular motion?

Back

a = v^2 / r, where a is acceleration, v is velocity, and r is radius.

Front

Calculate the acceleration of a car moving at 17 m/s on a circular track of 200 m radius.

Back

1.45 m/s²

Front

What is the acceleration of Bruno the bat with a mass of 0.58 kg flying at 0.8 m/s in a circle of radius 0.5 m?

Back

1.3 m/s²

Front

Do two riders on a circular ride travel the same distance with every loop?

Back

No, rider Y travels a greater circumference.

Front

Define mass in the context of physics.

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, keeping an object in circular motion.
