PHY-102 ENERGY AND CIRCULAR MOTION
ACTUAL EXAM PAPER 2026 QUESTIONS
SOLUTIONS GRADED A+
◉ What is uniform circular motion? Answer: Moving in a circle at a
constant speed.
◉ What is the formula for acceleration in circular motion? Answer:
ac = v²/r.
◉ What does a free body diagram (FBD) represent? Answer: It
shows all the forces acting on an object.
◉ What is the formula for gravitational force between two masses?
Answer: Fg = G(m1*m2)/r².
◉ What is the acceleration due to gravity on Earth's surface?
Answer: g = 9.8 m/s².
◉ What occurs during free fall? Answer: Only the force of gravity
acts on the object, resulting in an acceleration of -g.
