Reynolds Semester 1 Physics FINAL

Front

What happens to the force between two charged objects if the distance is reduced?

Back

The force increases. Specifically, if the distance is reduced from 30 cm to 10 cm, the force increases by a factor of 9.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.

Front

How do you calculate the radius of a loop given centripetal force, mass, and speed?

Back

Use the formula: F = (mv^2)/r, where F is the centripetal force, m is mass, v is speed, and r is the radius.

Front

What is the relationship between angular velocity and linear velocity?

Back

Linear velocity (v) is related to angular velocity (ω) by the formula: v = rω, where r is the radius.

Front

What happens to the force of friction if the mass of an object is increased while moving at constant velocity?

Back

The force of friction increases as it is directly proportional to the normal force, which increases with mass.

Front

What is the principle of equilibrium in physics?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

How do you convert revolutions per minute (rpm) to linear velocity?

Back

Use the formula: v = (2πr)(rpm/60), where r is the radius.

Front

What is the formula for calculating gravitational force between two masses?

Back

The formula is F = G(m1*m2)/r^2, where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv^2, where m is mass and v is velocity.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.
