Front

Back

Find the time when acceleration is 0, then calculate speed using the velocity function.

Front

When is a particle's speed decreasing?

Back

When its velocity and acceleration have different signs.

Front

What condition indicates that a particle is at rest?

Back

v(t) = 0.

Front

Define acceleration in the context of particle motion.

Back

Acceleration is the rate of change of velocity with respect to time.

Front

What does a positive acceleration indicate about a particle's velocity?

Back

The particle's velocity is increasing.

Front

What is the relationship between velocity and displacement?

Back

Velocity is the derivative of displacement with respect to time.

Front

How can you determine the maximum height of a particle's motion?

Back

Find the time when the velocity is 0, then substitute back into the displacement function.

Front

What does it mean if a particle's velocity is constant?

Back

The particle is moving at a steady speed in a straight line.
