Flashcard 7

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in a net force of zero. This means the object will not accelerate and will either remain at rest or continue moving at a constant speed.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or opposite in direction, resulting in a net force that causes an object to accelerate. This can change the object's speed or direction.

Front

What does acceleration mean in physics?

Back

Acceleration is the rate at which an object changes its velocity. It can be an increase or decrease in speed or a change in direction.

Front

How can you determine if an object is accelerating?

Back

An object is accelerating if its speed is changing, its direction is changing, or both. This can be observed through changes in position over time.

Front

What is a position-time graph?

Back

A position-time graph shows how the position of an object changes over time. The slope of the graph indicates the object's speed.

Front

What does a horizontal line on a position-time graph indicate?

Back

A horizontal line indicates that the object is at rest, meaning its position does not change over time.

Front

What does a steep slope on a position-time graph indicate?

Back

A steep slope indicates that the object is moving quickly, as it covers a large distance in a short amount of time.

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the distance traveled by the object during that time interval.

Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time, without speeding up or slowing down.

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.
