Acceleration

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 negative acceleration indicate?

Back

A negative acceleration indicates that the object is slowing down.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

What does a constant speed mean in terms of acceleration?

Back

A constant speed means that the acceleration is zero.

Front

How can you tell if an object is accelerating from a position vs. time graph?

Back

If the graph is curved, the object is accelerating. If it is a straight line, the object is moving at a constant speed.

Front

What is the unit of acceleration in the SI system?

Back

The unit of acceleration in the SI system is meters per second squared (m/s²).

Front

If an object is moving at a constant velocity, what is its acceleration?

Back

If an object is moving at a constant velocity, its acceleration is zero.

Front

What does it mean if the acceleration is positive?

Back

Positive acceleration means the object is speeding up.

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 happens to the acceleration of an object if the net force acting on it is zero?

Back

If the net force acting on an object is zero, its acceleration is also zero.
