Velocity and Acceleration Flashcard

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is the formula for calculating acceleration?

Back

a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

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 displacement?

Back

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

Front

What is the relationship between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight-line distance between the starting and ending points.

Front

What does it mean if an object is moving at a constant speed?

Back

It means the object covers equal distances in equal intervals of time without changing its speed.

Front

How do you determine the direction of acceleration in circular motion?

Back

In circular motion, acceleration is directed towards the center of the circle.

Front

What is the formula for final velocity when acceleration and time are known?

Back

V_f = (a • t) + V_i, where V_i is the initial velocity.
