Physics Flashcard 1

Front

What is a quality of a good scientific model?

Back

A good scientific model is simple and clearly explains something.

Front

In which unit is the position of objects measured?

Back

Position of objects is measured in meters.

Front

How can the velocity of a racer be described?

Back

The velocity of a racer can be described by comparing their speed to another racer, e.g., Racer 1 ran faster than Racer 2.

Front

How is the acceleration of an object calculated?

Back

The acceleration of an object can be calculated by dividing its velocity by the time that has passed.

Front

What makes a model better in demonstrating how an object is pushed?

Back

A better model is one that is simple and shows how objects move, such as Picture B.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

What does acceleration indicate about an object's motion?

Back

Acceleration indicates how quickly an object is changing its velocity.

Front

What is the SI unit of acceleration?

Back

The SI unit of acceleration is meters per second squared (m/s²).

Front

What is the relationship between distance, speed, and time?

Back

The relationship is described by the formula: Distance = Speed × Time.
