What is a free-body diagram?

Back

A free-body diagram is a graphical representation used to visualize the forces acting on an object. It shows all the external forces acting on the object, allowing for the analysis of the object's motion.

What happens to an object on a frictionless surface when a net force is applied?

Back

The object will accelerate in the direction of the net force applied to it.

Front

What is the relationship between buoyant force and weight for an object submerged in fluid?

Back

If the buoyant force is greater than the weight of the object, the object will rise. If the buoyant force is less than the weight, the object will sink.

Front

How do you determine the direction of the force of gravity on an object?

Back

The force of gravity always acts downward towards the center of the Earth, regardless of the object's position.

Front

What is the significance of the friction force when an object is at rest?

Back

The friction force acting on an object at rest is equal in magnitude and opposite in direction to the applied force, resulting in a net force of zero.

Front

What is the formula for calculating net force?

Back

Net force is calculated by summing all the forces acting on an object, taking into account their directions. Net Force = F_applied + F_friction + F_gravity + ...

Front

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, meaning all forces are balanced and the object is either at rest or moving with constant velocity.

Front

What is the principle of buoyancy?

Back

The principle of buoyancy states that an object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object.

Front

How does the angle of an inclined plane affect the forces acting on an object?

Back

The angle of an inclined plane affects the distribution of gravitational force into components parallel and perpendicular to the surface, influencing the object's acceleration and friction.

Front

What is the role of normal force in free-body diagrams?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.
