ECAT Physics — Motion and Force
Motion and Force is part of the Physics section of the UET ECAT (30 of the 100 MCQs). It breaks into 5 subtopics, and we hold 60 ECAT-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Motion and Force MCQs from the ECAT past papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · ECAT Past Paper 07 · Motion and Force
When you drop a ball it accelerates at 9.8 m/s². If you instead throw it downward, its acceleration immediately after leaving your hand (no air resistance) is:
- A.9.8 m/s²
- B.More than 9.8 m/s²
- C.Less than 9.8 m/s²
- D.None of these
Show answer
Answer: A. 9.8 m/s² — Only gravity acts after release: a = g.
- Q2 · ECAT Past Paper 06 · Motion and Force
When you drop a ball it accelerates downward at 9.8 m/s². If you instead throw it downward, its acceleration immediately after leaving your hand, assuming no air resistance, is:
- A.9.8 m/s²
- B.More than 9.8 m/s²
- C.Less than 9.8 m/s²
- D.Depends on throwing speed
Show answer
Answer: A. 9.8 m/s² — After release only gravity acts, so a = g = 9.8 m/s².
- Q3 · ECAT Past Paper 05 · Motion and Force
When you drop a ball it accelerates at 9.8 m/s². If you instead throw it downward, its acceleration immediately after leaving your hand (no air resistance) is:
- A.9.8 m/s²
- B.Less than 9.8 m/s²
- C.More than 9.8 m/s²
- D.Depends on the throwing speed
Show answer
Answer: A. 9.8 m/s² — After release only gravity acts, so a = g = 9.8 m/s² whatever the initial speed.
