Speed and Acceleration Problems

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is the unit of acceleration?

Back

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

Front

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

Back

A flat line indicates that the object is stationary, meaning it is not moving.

Front

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

Back

A steeper slope indicates a higher speed; the object is moving faster.

Front

How do you calculate distance using speed and time?

Back

Distance = Speed × 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 does it mean if an object is accelerating?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down, also known as deceleration.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.
