This worksheet explores the force acting on an object due to gravity, discussing key concepts such as speed, distance, and tension. Using the formula for speed (Speed = distance/time), we can calculate a speed of 26,667 km/h when covering 40,000 km in 1.5 hours. Additionally, the distance is determined as the area of a rectangle (A = length x width), producing a distance of 16 m for dimensions 8 m by 2 m. We also examine how tension in a string behaves under different forces. Engage with these calculations to better understand gravitational effects.
