Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve increasing speed, decreasing speed, or changing direction.

Front

What are the three types of acceleration?

Back

1. Positive acceleration (speeding up) 2. Negative acceleration (slowing down) 3. Centripetal acceleration (changing direction)

Front

What does it mean when an object is accelerating?

Back

An object is accelerating if it is changing its velocity, which includes speeding up, slowing down, or changing direction.

Front

Is it possible for an object to accelerate while moving at a constant speed?

Back

Yes, if the object is changing direction, it is still accelerating even if its speed remains constant.

Front

What is the formula for acceleration?

Back

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

Front

What is an example of negative acceleration?

Back

A car slowing down as it approaches a stop sign.

Front

What is an example of positive acceleration?

Back

A car speeding up as it moves from a stoplight.

Front

What does a flat line on a position vs. time graph indicate?

Back

A flat line indicates that the object is not moving; its position is constant over time.

Front

What does a steep slope on a position vs. time graph indicate?

Back

A steep slope indicates that the object is moving quickly; the steeper the slope, the faster the object is moving.

Front

What does a curve on a position vs. time graph indicate?

Back

A curve indicates that the object is accelerating; the slope of the curve represents the object's speed.
