Speed, Velocity Acceleration, Graphs

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve increasing speed, decreasing speed, or changing direction.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is staying still and not changing its position over time.

Front

If an object travels 100 m in 5 seconds, what is its average speed?

Back

Average speed = distance/time = 100 m / 5 s = 20 m/s.

Front

What is the formula to calculate acceleration?

Back

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

Front

What does a steep slope on a distance-time graph represent?

Back

A steep slope indicates that the object is moving quickly.

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.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

If a car is moving at a constant speed of 60 km/h, what is its acceleration?

Back

The acceleration is 0 m/s² because the speed is constant.

Front

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

Back

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

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).
