Front

What does the area under a velocity-vs-time graph represent?

Back

The area under a velocity-vs-time graph represents the displacement of the object.

Front

How can you determine the acceleration of an object from a force diagram?

Back

Acceleration can be determined using Newton's second law: a = F/m, where F is the net force and m is the mass of the object.

Front

What does the y-intercept of a velocity-vs-time graph indicate?

Back

The y-intercept of a velocity-vs-time graph indicates the initial velocity of the object.

Front

What is the relationship between velocity and acceleration?

Back

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

Front

What does a flat line on a velocity-vs-time graph indicate?

Back

A flat line indicates that the object is moving at a constant velocity.

Front

What is the significance of the slope of a velocity-vs-time graph?

Back

The slope of a velocity-vs-time graph represents the acceleration of the object.

Front

How do you find the initial velocity from a velocity-vs-time graph?

Back

The initial velocity is found by looking at the height of the graph at time t = 0.

Front

What does a negative acceleration indicate about an object's motion?

Back

Negative acceleration indicates that the object is slowing down.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no air resistance.

Front

What does a downward slope on a velocity-vs-time graph indicate?

Back

A downward slope indicates that the object is decelerating or slowing down.
