1 D Motion

Front

What is 1D motion?

Back

1D motion refers to the movement of an object along a straight line, where only one dimension is considered (e.g., forward or backward).

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a steady speed in a straight line without changing its direction.

Front

What does a velocity vs. time graph represent?

Back

A velocity vs. time graph shows how the velocity of an object changes over time, with the slope representing acceleration.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can be positive (speeding up) or negative (slowing down).

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an 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 other forces acting on it.

Front

How far does an object fall in free fall after 3.5 seconds?

Back

An object falls approximately 61 meters in free fall after 3.5 seconds.

Front

What is the relationship between slope and acceleration on a velocity vs. time graph?

Back

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

Front

What happens to the direction of acceleration when an object is slowing down?

Back

When an object is slowing down, the direction of acceleration is opposite to the direction of motion.
