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

Back

As the difference between the two masses increases, the acceleration of the Atwood machine increases.

What does it mean for an object to be in equilibrium?

Back

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

If a force of 8 Newtons is applied to a crate moving at a constant velocity, what can be said about the frictional force?

Back

The magnitude of the frictional force is equal to the applied force, which is 8 N.

What does a Free Body Diagram (FBD) represent?

Back

A Free Body Diagram (FBD) represents all the forces acting on an object, helping to analyze its motion.

How can you determine if an elevator is at rest using FBDs?

Back

An elevator is at rest if the forces acting on it are balanced, resulting in no net force.

Front

What is the net force acting on an object moving at constant velocity?

Back

The net force acting on an object moving at constant velocity is 0 N.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula a = (final velocity - initial velocity) / time.

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

What is the significance of friction in motion?

Back

Friction opposes the motion of an object and is crucial for understanding how forces interact in dynamics.

Front

What factors affect the acceleration of an object?

Back

The acceleration of an object is affected by the net force acting on it and its mass.
