Acceleration Flashcard Practice

Front

What is the SI unit for acceleration?

Back

m/s²

Front

How is acceleration defined?

Back

Acceleration is the change in velocity of an object divided by the time interval.

Front

What is a correct measure of velocity?

Back

40 kn/hr north

Front

What is the equation for acceleration?

Back

Acceleration (a) = (Final Velocity (v_f) - Initial Velocity (v_i)) / Time (t)

Front

Which graph represents the greatest acceleration?

Back

Graph A represents the greatest acceleration.

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object's velocity is increasing.

Front

What does a negative acceleration (deceleration) indicate?

Back

A negative acceleration indicates that an object's velocity is decreasing.

Front

What is the relationship between acceleration and force?

Back

According to Newton's second law, acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass (F = ma).

Front

What is the formula to calculate distance when acceleration is constant?

Back

Distance (d) = Initial Velocity (v_i) * Time (t) + 0.5 * Acceleration (a) * Time² (t²)

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.
