Unit 7 Flashcard Review Force and Motion

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled by an object, while displacement is the shortest straight line from the initial to the final position, including direction.

Front

How do you calculate acceleration?

Back

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

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: speed = distance / time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does a constant velocity indicate?

Back

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

Front

What is the significance of a stop sign in motion?

Back

A stop sign indicates that a vehicle must come to a complete stop, which affects its velocity and acceleration.

Front

How do you determine the time taken to travel a certain distance at a constant speed?

Back

Time can be determined using the formula: time = distance / speed.

Front

What is the relationship between speed, distance, and time?

Back

The relationship is defined by the formula: distance = speed × time.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed of an object at a specific moment in time.
