Front

What is an Atwood machine?

Back

An Atwood machine is a device consisting of two masses connected by a string over a pulley, used to study the effects of gravity and acceleration.

Front

What happens to the tension in the string of an Atwood machine when the masses are unequal?

Back

The tension in the string is the same on both sides, regardless of the mass difference.

Front

Which mass moves downward in an Atwood machine when the masses are unequal?

Back

The greater mass moves downward.

Front

What is the direction of the normal force acting on an object resting on a surface?

Back

The normal force always acts perpendicular to the surface, pointing upward.

Front

What is the direction of the weight force acting on an object?

Back

The weight force always acts downward due to gravity.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

In which direction does friction act when an object is sliding to the right?

Back

Friction acts to the left, opposing the motion.

Front

What is the role of drag in a system?

Back

Drag is a force that opposes the motion of an object through a fluid, such as air or water.

Front

What is the relationship between mass and acceleration in an Atwood machine?

Back

The acceleration of the system is determined by the difference in mass and the gravitational force acting on them.

Front

What is the formula for calculating the net force in an Atwood machine?

Back

Net force (F_net) = (m1 - m2) * g, where m1 and m2 are the masses and g is the acceleration due to gravity.
