Question 1: Physical Quantity Measured in Newton

Question:
Which physical quantity is measured in Newton?

Explanation

Newton (N) is the SI unit for force. It was named after Sir Isaac Newton due to his work on motion and gravitation.

• 1 Newton = the force required to accelerate 1 kg of mass by 1 m/s².

Correct Answer: Force

Question 2: Slope of a Distance-Time Graph

Question:
The slope of a distance-time graph represents what?

Explanation

• The slope of a distance-time graph is calculated as change in distance / change in time.
• This represents speed (rate of change of distance).

Correct Answer: Speed

Question 3: Acceleration Due to Gravity on Earth

Question:
What is the acceleration due to gravity on Earth?

Explanation

• The standard value of acceleration due to gravity on Earth is 9.8 m/s².
• Often approximated as 10 m/s² for calculations in IGCSE physics.

Correct Answer: 9.8 m/s²

Question 4: Average Speed Calculation

Question:
A car travels 100 km in 2 hours. What is its average speed?

Solution

Average speed = distance ÷ time 100 km÷2 h=50 km/h

Correct Answer: 50 km/h

Question 5: Device Used to Measure Electric Current

Question:
Which device is used to measure electric current?

Explanation

• Voltmeter: Measures voltage (potential difference)
• Ammeter: Measures electric current
• Galvanometer: Measures small currents

Correct Answer: Ammeter
