Constant Acceleration Review

Front

What is constant acceleration?

Back

Constant acceleration refers to a situation where an object's velocity changes at a consistent rate over time.

Front

What is the formula for calculating distance under constant acceleration?

Back

The formula is: d = v_i * t + 0.5 * a * t^2, where d is distance, v_i is initial velocity, a is acceleration, and t is time.

Front

How do you calculate final velocity with constant acceleration?

Back

The formula is: v_f = v_i + a * t, where v_f is final velocity, v_i is initial velocity, a is acceleration, and t is time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a car accelerates at -2.00 m/s² for 10 seconds, what is its change in velocity?

Back

The change in velocity is -20 m/s.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the distance traveled.

Front

How do you determine the distance traveled when an object comes to a stop?

Back

Use the formula: d = (v_i^2) / (2 * a), where v_i is initial velocity and a is acceleration.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with an acceleration of approximately 9.81 m/s².

Front

What is the final speed of an object dropped from a height of 11 meters?

Back

The final speed is approximately 15 m/s just before it hits the ground.
