Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is a vector quantity, meaning it has both magnitude and direction.

Front

How do you calculate acceleration when an object comes to a stop?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time. For an object coming to a stop, the final velocity is 0.

Convert 41 inches to centimeters.

Back

41 inches = 104.14 cm (using the conversion factor 1 in = 2.54 cm).

Front

What is the relationship between milligrams and grams?

Back

1 gram = 1000 milligrams. Therefore, to convert milligrams to grams, divide by 1000.

Front

What does a constant speed graph look like?

Back

A constant speed graph is represented by a straight line with a constant slope on a distance-time graph.

Front

What are basic quantities in physics?

Back

Basic quantities are fundamental physical quantities that cannot be defined in terms of other quantities. Examples include length, mass, time, and temperature.

Front

What is the formula for converting inches to centimeters?

Back

The formula is: centimeters = inches × 2.54.

Front

What is the significance of negative acceleration?

Back

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

Front

How do you determine the speed of an object from a graph?

Back

The speed of an object can be determined by calculating the slope of the distance-time graph.

Front

What is the unit of acceleration in the SI system?

Back

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