Basic Physics Quiz — Forces, Motion & Energy | Science
Tests foundational knowledge of forces, motion, and energy.
Welcome to the Basic Physics Quiz, a concise evaluation designed to test foundational knowledge of forces, motion, and energy. This Science-focused assessment covers core concepts including Newton's laws, kinematics, dynamics, work and energy, and momentum. Whether you're a student preparing for exams or an enthusiast refreshing essential physics principles, this quiz helps you pinpoint strengths and areas for improvement.
By answering these multiple-choice questions, you'll reinforce critical physics vocabulary and problem-solving intuition while getting an immediate score-based evaluation. The quiz is optimized to help learners master mechanics fundamentals — forces, acceleration, units, conservation laws — and is ideal for intro-level review, classroom warm-ups, or self-assessment. Ready to measure your understanding of basic physics concepts?
Which of the following statements best expresses Newton's second law of motion?
Identify the law that relates net force, mass, and acceleration.
What is the SI unit of force?
Choose the correct standard unit used for force in the International System (SI).
A 2 kg object accelerates at 3 m/s². What is the net force acting on the object?
Apply F = ma to compute net force.
Which of the following graph descriptions indicates constant velocity?
Consider standard position-time and velocity-time graph shapes.
What does the law of conservation of energy state for a closed system?
Select the principle that describes energy behavior in a closed system.
If a constant force acts perpendicular to an object's displacement, what is the work done by that force?
Recall the definition W = F·d·cos(theta).
Which of the following quantities is a scalar?
Identify the quantity that has magnitude only, not direction.
What is the correct expression for kinetic energy of a moving object?
Choose the formula for kinetic energy in classical mechanics.
If the net force on an object is zero, what will the object do?
Apply Newton's first law to determine the motion of the object.
Impulse is defined as which of the following?
Recall the relationship between impulse, force, time, and momentum.
Frequently asked questions
Your score is calculated by summing the numeric values assigned to each selected option. The quiz uses a simple additive model: higher totals indicate stronger mastery of the basic physics topics covered (forces, motion, energy, work, and momentum).
Scores are grouped to indicate proficiency: 0–7 suggests beginner level and recommends focused review; 8–14 indicates intermediate understanding with room for practice; 15–20 represents strong foundational knowledge. Use the results_description for specific study recommendations.
Yes — retaking the quiz after studying is encouraged. It helps measure improvement, reinforce concepts, and identify remaining gaps in understanding. Try targeted practice on areas where your initial score was lower.
This quiz is designed as a brief conceptual and calculation check. For best self-assessment, you can use scratch paper, a basic calculator, or formula sheets, but try to rely on understanding first and use tools only as needed.
Focus on Newton's laws, kinematics (displacement, velocity, acceleration), dynamics (F = ma), work and energy (including W = Fd cosθ and kinetic/potential energy), and momentum/impulse. Practice unit conversions and basic numerical problems.
The Basic Physics Quiz is best for quick review and self-assessment of foundational mechanics concepts. For exam preparation, supplement it with problem sets, detailed textbooks, and practice exams that cover a broader and deeper range of questions.
