Physics - Motion

Front

What is the formula for average speed?

Back

Average speed = Total distance / Total time.

Front

Define positive acceleration.

Back

Positive acceleration occurs when an object's speed increases over time.

Front

What is the relationship between acceleration, change in speed, and time?

Back

Acceleration = Change in speed / Time.

Front

Convert 65 grams to milligrams.

Back

65 grams = 65,000 milligrams.

Front

What is an example of constant speed?

Back

A truck driving straight and using cruise control.

Front

What is the unit of acceleration in the SI system?

Back

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

Front

What does it mean when an object is in motion?

Back

An object is in motion if its position changes relative to a reference point.

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 acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time.

Front

What is the significance of a negative acceleration?

Back

Negative acceleration, or deceleration, indicates that an object is slowing down.
