What are significant figures?

Back

Significant figures are the digits in a number that contribute to its precision. This includes all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion.

Front

How do you determine the number of significant figures in a measurement?

Back

Count all non-zero digits, any zeros between them, and trailing zeros in a decimal number. Leading zeros are not counted.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time, measured in meters per second squared (m/s²).

Front

What is the equation of motion for displacement?

Back

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down or decelerating.

Front

How do you calculate displacement when initial velocity is zero?

Back

Front

What is the significance of the time variable in motion equations?

Back

The time variable is crucial as it determines how long an object has been in motion, affecting both velocity and displacement.

Front

What is the formula for calculating final velocity?

Back

Front

What is the relationship between velocity and acceleration?

Back

Velocity is the speed of an object in a given direction, while acceleration is the rate at which that velocity changes over time.
