Particle Motion

Front

What does it mean when an object is accelerating?

Back

An object is accelerating when its velocity is changing over time, which can mean it is speeding up, slowing down, or changing direction.

Front

What is the relationship between velocity and acceleration when a particle's speed is decreasing?

Back

When a particle's speed is decreasing, its velocity and acceleration have different signs.

Front

What does v(t) > 0 indicate about a particle's motion?

Back

v(t) > 0 means the particle is moving to the right.

Front

How do you determine the total distance traveled from a motion graph?

Back

The total distance is the sum of all segments of the graph, regardless of direction.

Front

What does it mean for a particle to have positive velocity?

Back

A particle has positive velocity if its position graph is increasing.

Front

Define 'acceleration'.

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does a flat line on a position-time graph represent?

Back

A flat line on a position-time graph indicates that the object is at rest.

Front

What is the significance of a negative acceleration?

Back

Negative acceleration indicates that an object is slowing down if it is moving in the positive direction.

Front

How can you tell if an object is decelerating?

Back

An object is decelerating if its velocity is positive and its acceleration is negative.
