10 Identify which force is acting on the apple as it falls in the absence of air friction in the picture below?

1.1.10 As the apple falls in the absence of air friction, the only force acting on it is the force of gravity, which pulls it towards the Earth.
The correct force is:
B) Gravitational force

1.1.11 According to Newton's First Law of Motion, if the net force acting on an object is zero (forces are balanced), the object will either remain at rest or continue to move at a constant velocity (constant speed in a straight line).
The object will:
C) Move at constant speed or remain at rest

1.2.1 The opposition to the flow of charge in a circuit is called resistance.

1.2.2 Materials that allow the flow of charge in a circuit are called conductors.

1.2.3 A group of electric cells connected together is called a battery.

1.2.4 The three factors that affect the resistance of a conductor are:

• Length of the conductor
• Cross-sectional area of the conductor
• Type of material (resistivity) of the conductor

1.2.5 Two advantages of connecting light bulbs in parallel in a house are:

• Each light bulb receives the full supply voltage, allowing it to operate at its intended brightness.
• If one light bulb fuses or is switched off, the other light bulbs in the circuit continue to operate independently.
