What does FBD stand for in physics, and what is its purpose?

Back

FBD stands for Free Body Diagram. It is used to show all the forces acting on an object, helping to analyze the object's motion.

What condition must be met for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, meaning all forces are balanced.

Front

What is inertia, and how does it relate to motion?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object in motion will stay in motion unless acted upon by an external force.

How does the angle of incline affect the force acting down the plane?

Back

The force acting down the plane increases as the angle of incline increases, due to the component of gravitational force acting along the incline.

Front

What is the formula for calculating the force acting down an inclined plane without friction?

Back

The formula is F = m * g * sin(θ), where F is the force down the plane, m is the mass, g is the acceleration due to gravity, and θ is the angle of incline.

What happens to the acceleration of an Atwood machine when the mass difference increases?

Back

The acceleration of the Atwood machine increases as the difference between the two masses increases.

What is the role of gravity in the motion of a thrown object?

Back

Gravity acts as a downward force on the object, affecting its upward motion and eventually causing it to decelerate and fall back down.

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as W = m * g, where W is weight, m is mass, and g is the acceleration due to gravity.

Front

What is the significance of the net force in determining an object's acceleration?

Back

The net force acting on an object determines its acceleration according to Newton's second law, F = m * a, where F is net force, m is mass, and a is acceleration.

What is the difference between static and dynamic equilibrium?

Back

Static equilibrium refers to an object at rest with no net forces acting on it, while dynamic equilibrium refers to an object moving at constant velocity with balanced forces.
