Front

What is the formula to calculate final velocity?

Back

The formula to calculate final velocity is: \( v_f = v_0 + at \), where \( v_f \) is final velocity, \( v_0 \) is initial velocity, \( a \) is acceleration, and \( t \) is time.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as velocity or force.

Front

What is the formula for speed?

Back

The formula for speed is: \( \text{speed} = \frac{\text{distance}}{\text{time}} \).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that refers to how much ground an object has covered, while displacement is a vector quantity that refers to how far out of place an object is.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the unit of velocity?

Back

The unit of velocity is meters per second (m/s).

Front

What is the relationship 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 does the slope of a distance-time graph represent?

Back

The slope of a distance-time graph represents the speed of the object.

Front

What is the formula for calculating acceleration?

Back

The formula for calculating acceleration is: \( a = \frac{\Delta v}{t} \), where \( \Delta v \) is the change in velocity and \( t \) is the time taken.
