Challenge Problems
Push your limits with challenges.
Question 1
A box is pulled across the floor with a force of 50 N, but friction opposes this with a force of 30 N. Calculate the net force acting on the box.
💡 Hint: Use the formula: Net force = Applied force - Frictional force.
Question 2
If you double the mass of an object, how does the gravitational force affecting it change? What does this imply for lifting the object?
💡 Hint: Consider the relationship between mass and gravitational acceleration.
