Analyzing Forces and Resultant Magnitude

The video tutorial explains how to calculate the resultant force acting on an object with multiple forces. It covers the analysis of collinear and non-collinear forces, the calculation of net horizontal and vertical forces, and the determination of the resultant force's magnitude and direction using trigonometry. The lesson concludes with a summary of the findings.

What is the primary objective when analyzing the forces acting on an object?

• To calculate the resultant force

• To measure the temperature of the object

• To determine the mass of the object

• To find the velocity of the object

Which of the following pairs of forces are considered collinear?

• 275 N and 45 N

• 16 N and 275 N

• 135 N and 45 N

• 16 N and 135 N

Why can't non-collinear forces be added directly?

• They are perpendicular to each other

• They are acting on different objects

• They are in the same direction

• They have the same magnitude

How is the net force in the horizontal direction calculated?

• By subtracting the smaller force from the larger force

• By adding all forces acting vertically

• By adding the forces acting along the x-axis

• By multiplying the forces acting along the y-axis

What is the net horizontal force if the forces are 275 N and -60 N?

• 275 N

• 250 N

• 215 N

• 335 N

What is the direction of the net vertical force if it is positive?

• Downwards

• To the left

• Upwards

• To the right

How is the resultant force represented on a Cartesian plane?

• As a vector with magnitude and direction

• As a circle

• As a single point

• As a line parallel to the x-axis

Which theorem is used to calculate the magnitude of the resultant force?

• Pythagorean theorem

• Bernoulli's equation

• Archimedes' principle

• Newton's law

What is the angle of the resultant force with respect to the positive x-axis?

• 90 degrees

• 45 degrees

• 60 degrees

• 22.71 degrees

What is the magnitude of the resultant force calculated in the lesson?

• 233.08 N

• 273.08 N

• 250 N

• 215 N
