Questions and Answers

Explain what inertia is and provide an example from everyday life.

Inertia is the resistance to a change in motion. An example from everyday life is the feeling of a jerk when brakes are applied in a car or a bus, where the body tries to continue moving forward but the seat belt applies a force that slows it down.

Describe a demonstration of inertia using an experiment.

A demonstration of inertia can be done using a glass or a cup of water, a coin, and a piece of card. When the card is pulled, the coin falls into the glass because the inertia of the coin maintains its state at rest, and as long as the friction between the card and the coin is not too high, it falls in.

What did Albert Einstein mean by 'nothing happens until something moves'?

Einstein meant that in order for any change to occur, some form of motion or action is necessary to initiate it.

How does inertia affect objects at rest and in motion?

Study Notes

Inertia

  • Albert Einstein's quote: "Nothing happens until something moves"
  • Inertia is the resistance to a change in motion
  • An object at rest remains at rest, and an object in motion remains in motion with the same velocity, unless acted upon by an unbalanced force

Effects of Inertia

  • Feeling a jerk when brakes are applied in a car or bus due to inertia
  • Inertia causes the body to try to continue moving forward, but the seat belt slows it down

Demonstrating Inertia

  • Experiment: using a glass or cup of water, a coin, and a piece of card
  • When the card is pulled, the coin falls into the glass due to its inertia maintaining its state at rest
  • The friction between the card and the coin must not be too high for the experiment to work
