Front

What happens to the lights in a series circuit if one bulb is removed?

Back

The rest of the lights will go out.

Front

What does the speedometer in a car measure?

Back

Instantaneous speed.

Front

Which material has a higher specific heat: Water (4184 J/KgºC) or Wood (1760 J/KgºC)?

Back

Water needs more energy to raise the temperature 1ºC.

Front

What does a graph representing constant speed look like?

Back

It shows a straight line with a constant slope.

Front

What type of friction is involved when pushing a box across the floor?

Back

Sliding friction.

Front

Define a series circuit.

Back

A circuit where all components are connected end-to-end, so the current flows through each component.

Front

What is instantaneous speed?

Back

The speed of an object at a specific moment in time.

Front

Explain specific heat capacity.

Back

The amount of energy required to raise the temperature of 1 kg of a substance by 1ºC.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is total distance divided by total time, while instantaneous speed is the speed at a specific moment.

Front

What does a graph showing acceleration look like?

Back

It shows a curve that slopes upwards, indicating an increase in speed.
