Acceleration and Speed Graphs

Front

What is acceleration?

Back

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

Front

What does a flat line on a speed graph indicate?

Back

A flat line indicates that the object is moving at a constant speed.

Front

How do you calculate acceleration?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

What does a steep slope on a speed graph represent?

Back

A steep slope indicates a high rate of acceleration or deceleration.

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 downward slope on a speed graph indicate?

Back

A downward slope indicates that the object is decelerating or slowing down.

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = distance / time = 100 m / 5 s = 20 m/s.

Front

What does it mean if an object has zero acceleration?

Back

Zero acceleration means the object is either at rest or moving at a constant speed.

Front

What is the formula for calculating distance when acceleration is involved?

Back

Distance can be calculated using the formula: d = initial velocity * time + 0.5 * acceleration * time².
