Physics Flashcard 5

Front

What does the temperature of an object describe?

Back

The motion of the molecules in the object.

Front

Which of the following is an example of a force?

Back

Friction.

Front

How do you calculate the weight of a 10kg object on Earth?

Back

Multiply 10kg by 9.8m/s/s.

Front

What happens to the molecules of textbooks when they are rubbed together?

Back

The molecules will move faster.

Front

How can you determine the strength of the friction on a block with a mass of 2,267 kg dragged across dry sand with a coefficient of friction of 0.58?

Back

Find the weight of the block, then multiply it by 0.58.

Front

Define 'force' in physics.

Back

A push or pull on an object resulting from its interaction with another object.

Front

What is the formula for calculating weight?

Back

Weight = Mass × Gravitational Acceleration (W = m × g).

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

Explain the concept of friction.

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

What is kinetic energy?

Back

The energy that an object possesses due to its motion.
