Section B Theory:
Question: What is Newton’s first law of motion, and provide an example?
Answer: Newton’s first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. An example is a book resting on a table; it will remain stationary unless an external force, like someone pushing it, is applied.
Question: Define momentum and explain how it is related to Newton’s second law of motion.
Answer: Momentum is the product of an object’s mass and its velocity. It is related to Newton’s second law of motion because according to the second law, the force acting on an object is equal to the rate of change of its momentum with time. Mathematically, this is expressed as F = Δp/Δt, where F is the force, Δp is the change in momentum, and Δt is the change in time.
Question: Describe the difference between scalar and vector quantities, providing examples of each.
Answer: Scalar quantities have only magnitude, while vector quantities have both magnitude and direction. Examples of scalar quantities include mass, temperature, and speed. Examples of vector quantities include displacement, velocity, and force.
Question: Explain the concept of work in physics and provide its formula.
Answer: In physics, work is defined as the product of force and displacement in the direction of the force applied. Mathematically, it is represented as W = F × d, where W is the work done, F is the force applied, and d is the displacement.
Question: Describe the difference between potential energy and kinetic energy, providing examples of each.
Answer: Potential energy is the energy an object possesses due to its position or condition, while kinetic energy is the energy of motion. Examples of potential energy include gravitational potential energy (a book held above the ground) and elastic potential energy (a stretched spring). Examples of kinetic energy include the energy of a moving car and the energy of a swinging pendulum.
FAQs
What is included in Physics JAMB past questions and answers?
Physics JAMB past questions and answers typically include both objective questions (multiple-choice) and theory questions. The objective questions cover topics such as Mechanics, Thermodynamics, Optics, Electricity and Magnetism, and Modern Physics, while theory questions often require detailed explanations, derivations, or problem-solving skills.
