Card 1
Question: What does the slope of a velocity-time (v-t) graph represent for uniformly accelerated motion?
Answer: The constant acceleration.
Card 2
Question: What does the area under a velocity-time (v-t) graph represent?
Answer: Displacement.
Card 3
Question: What is free fall?
Answer: The motion of an object under the sole influence of gravity.
Card 4
Question: What is the standard value for gravitational acceleration (g) near the Earth's surface?
Answer: Approximately 9.81 m/s².
Card 5
Question: What does it mean for an object's velocity to increase by 9.81 m/s every second in free fall?
Answer: Its downward velocity increases by 9.81 m/s for every second it is in free fall.
Card 6
Question: What is dynamics in physics?
Answer: The study of the relationship between forces and the motion they cause.
Card 7
Question: Which law connects force and motion in the most fundamental way?
Answer: Newton's Second Law of Motion.
Card 8
Question: State Newton's Second Law of Motion.
Answer: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The direction of the acce
Card 9
Question: What is the key formula for Newton's Second Law of Motion?
Answer: F = m · a
Card 10
Question: What does 'F' represent in Newton's Second Law formula (F=ma) and what are its units?
Answer: F is the net force acting on the object, measured in Newtons (N).
