What is the kinematic equation for displacement when initial velocity, acceleration, and time are known?

Back

d = v_i * t + 1/2 * a * t^2

Front

What does the variable 'v_f' represent in kinematic equations?

Back

Final velocity

Front

If a car is moving at a velocity of 40 m/s and then comes to a stop, what is its initial velocity?

Back

40 m/s

Front

What is the kinematic equation that relates final velocity, initial velocity, acceleration, and displacement?

Back

v_f^2 = v_i^2 + 2 * a * d

Front

What is the average velocity formula in terms of displacement and time?

Back

d = (v_f + v_i) / 2 * t

Front

What does 'a' represent in kinematic equations?

Back

Acceleration

Front

What is the significance of the term '1/2' in the displacement equation?

Back

It accounts for the average velocity when acceleration is constant.

Front

How do you calculate the final velocity if you know the initial velocity, acceleration, and time?

Back

v_f = v_i + a * t

Front

What is the relationship between acceleration and velocity in kinematic equations?

Back

Acceleration is the rate of change of velocity.

Front

What is the unit of acceleration in the SI system?

Back

meters per second squared (m/s^2)
