Forces in 2 Dimension

Front

What is the normal force?

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.

Front

How do you calculate the normal force on an inclined plane?

Back

F_N = mg cos(ϴ), where m is mass, g is acceleration due to gravity, and ϴ is the angle of the incline.

Front

What is the role of the angle in determining the normal force?

Back

The angle affects the distribution of weight between the normal force and the gravitational force acting on the object.

Front

What is the relationship between applied force and normal force?

Back

The normal force can change based on the applied force, especially if the force has a vertical component.

Front

How do you resolve a force into its components?

Back

To resolve a force, use trigonometric functions: F_x = F cos(ϴ) and F_y = F sin(ϴ), where F is the magnitude of the force.

Front

What is equilibrium in the context of forces?

Back

Equilibrium occurs when the net force acting on an object is zero, meaning all forces are balanced.

Front

How do you find the magnitude of the resultant force?

Back

Use the Pythagorean theorem: R = √(F_x² + F_y²), where F_x and F_y are the horizontal and vertical components of the forces.

Front

What is the significance of the angle in force problems?

Back

The angle determines how much of the force acts in the horizontal and vertical directions, affecting the normal force and equilibrium.

Front

What is the formula for calculating the horizontal component of a force?

Back

F_x = F cos(ϴ), where F is the total force and ϴ is the angle with respect to the horizontal.

Front

What is the formula for calculating the vertical component of a force?

Back

F_y = F sin(ϴ), where F is the total force and ϴ is the angle with respect to the horizontal.
