Motion REVIEW (Finals)

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is measured in meters per second squared (m/s²).

Front

How do you calculate distance when an object accelerates uniformly from rest?

Back

Use the formula: Distance = 0.5 * acceleration * time².

Front

What is the formula for calculating acceleration?

Back

Acceleration = (final velocity - initial velocity) / time.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the change in position from the initial to the final point.

Front

What does it mean if an object has a constant velocity?

Back

It means the object is moving at the same speed in a straight line without changing direction.

Front

What is the acceleration of an object moving at constant velocity?

Back

0 m/s², because there is no change in velocity.

Front

What happens to an object's speed if it has a negative acceleration?

Back

The object is slowing down.

Front

Define displacement in terms of motion.

Back

Displacement is the vector quantity that refers to the change in position of an object, measured from the initial to the final position.

Front

What is the significance of the direction of acceleration?

Back

If acceleration is in the same direction as velocity, the object speeds up; if it is in the opposite direction, the object slows down.

Front

What is the unit of measurement for velocity?

Back

Meters per second (m/s).
