12/3 Acceleration Practice

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur when an object speeds up, slows down, or changes direction.

Front

True or False: Acceleration only occurs when an object speeds up.

Back

False. Acceleration can also occur when an object slows down or changes direction.

Front

What does a negative change in velocity indicate?

Back

A negative change in velocity indicates that the object is slowing down.

Front

If an object has a positive velocity and a positive acceleration, what is happening?

Back

The object is speeding up.

Front

What is the formula for calculating acceleration?

Back

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

Front

If a car is moving at a constant speed, what is its acceleration?

Back

The acceleration is 0 m/s² because there is no change in velocity.

Front

What is the unit of acceleration in the International System of Units (SI)?

Back

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

Front

If an object is changing direction but maintaining speed, does it have acceleration?

Back

Yes, changing direction while maintaining speed means the object is accelerating.

Front

What is the acceleration of a dog that runs with an initial speed of 7.5 m/s and slides to a stop in 15 seconds?

Back

The acceleration is -0.5 m/s².

Front

What does it mean if an object has a negative acceleration?

Back

Negative acceleration means the object is slowing down.
