Flashcard on Space Travel

Front

What is the difference between weight and mass?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in an object and is constant regardless of location.

Front

State Newton's First Law of Motion.

Back

An object in motion remains in motion at the same speed and direction unless acted upon by a net force.

Front

What is the formula to calculate force?

Back

Force = mass × acceleration (F = m × a).

Front

Define mass in terms of matter.

Back

Mass is the amount of matter in an object and is constant for most objects.

Front

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

Back

Kilogram (kg).

Front

How does mass affect acceleration in a collision?

Back

In a collision, the greater the mass of an object, the less it will accelerate when a force is applied.

Front

What is the acceleration of a 2.0 kg cart exerting a 10 N force?

Back

5 m/s² (using F = m × a).

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.

Front

What is the gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

What does it mean for a track to be frictionless?

Back

A frictionless track allows objects to move without any resistance, making it ideal for studying motion.
