Front

What are the three types of acceleration?

Back

1. Speeding up (positive acceleration) 2. Slowing down (negative acceleration) 3. Changing directions (centripetal acceleration)

Front

What happens to a car's acceleration when it rounds a corner at constant speed?

Back

The car accelerates because its direction changes.

Front

How is acceleration measured?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

What does it mean if an object is accelerating?

Back

It means that the object's speed is changing, whether it's increasing, decreasing, or changing direction.

Front

What is the formula for calculating acceleration?

Back

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

Front

Can an object be accelerating if its speed is constant?

Back

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

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 is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, experienced by an object moving in a circle.
