Resultant Forces (GCSE Physics)

A box on a table has weight 150 N downward and the table exerts a normal contact force of 150 N upward. What is the resultant vertical force on the box?

Two forces of 7 N and 24 N act at an angle of 90° to each other. What is the magnitude of the resultant?

A block on a slope experiences gravity component 40 N down the slope and friction 25 N up the slope. What is the resultant along the slope and will the block accelerate up or down?

A book rests on a table with gravitational force 12 N downward. A student pushes down on the book adding another 3 N downward. The table reacts with normal force. What is the normal force?

A tug-of-war team pulls left with 420 N while the other team pulls right with 300 N. What is the resultant force and direction?

A lift is held stationary by the cable. The lift’s weight is 9800 N downward and the cable pulls 9800 N upward. If the lift motor stops and the cable suddenly provides 9600 N upward, what is the resultant force and acceleration direction?

A cyclist applies a forward force of 200 N. Air resistance and friction total 200 N backward. What is the cyclist’s acceleration?

Two forces of 5 N and 12 N act along the same line in the same direction. What is their resultant?

A student applies a 10 N push at the centre of a uniform disk causing no rotation and the disk remains at constant speed. What is the resultant horizontal force?

Two 8 N forces act on a point separated by 120°. What is the magnitude of the resultant? (Resultant = sqrt(8^2+8^2+2·8·8·cos120°))

Two people push a table from opposite sides with equal magnitude forces so it doesn’t move. If one person increases their push, what happens to the resultant force?
