PHYS 2.1 - Motion in One Dimension

Front

What is displacement?

Back

Displacement is the change in position of an object, defined as the shortest distance from the initial to the final position, along with the direction.

Front

What is the formula for average velocity?

Back

Average velocity is calculated as the total displacement divided by the total time taken: \( v_{avg} = \frac{\Delta x}{\Delta t} \).

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 as the distance traveled divided by the time taken: \( speed = \frac{distance}{time} \).

Front

What is acceleration?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated as the change in velocity divided by the time taken: \( a = \frac{\Delta v}{\Delta t} \).

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction, such as displacement, velocity, and force.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude and no direction, such as distance, speed, and mass.

Front

How do you calculate displacement from a velocity-time graph?

Back

Displacement can be found by calculating the area under the velocity-time graph.

Front

What is the significance of a negative displacement?

Back

A negative displacement indicates that the object has moved in the opposite direction from the reference point.
