Speed and Acceleration Problems

Front

What is acceleration?

Back

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

Front

How do you calculate acceleration?

Back

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

Front

What is the formula for speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

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 is a unit of speed?

Back

Common units of speed include meters per second (m/s) and kilometers per hour (km/h).

Front

How do you convert miles per hour to meters per second?

Back

To convert miles per hour (mi/hr) to meters per second (m/s), multiply by 0.44704.

Front

What does it mean if an object is stationary?

Back

An object is stationary if it is not moving and its velocity is zero.

Front

What does it mean if an object is accelerating?

Back

An object is accelerating if it is changing its velocity, which can mean speeding up, slowing down, or changing direction.

Front

What is the distance traveled by an object moving at a constant speed?

Back

Distance can be calculated using the formula: Distance = Speed x Time.

Front

What is the significance of a negative acceleration?

Back

Negative acceleration indicates that an object is slowing down.
