Physics

Question: What is Newton’s first law of motion?
Answer: Newton’s first law of motion states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.

Question: What is the formula for force?
Answer: The formula for force is F = ma, where m is mass and a is acceleration.

Question: Define work in physics.
Answer: Work is done when a force is applied to an object, causing it to move. It is calculated as work = force × distance.

Question: What is the difference between speed and velocity?
Answer: Speed is the rate at which an object moves, while velocity is speed in a specific direction.

Question: What is Ohm’s law?
Answer: Ohm’s law states that the current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance.
