Acceleration

Front

What is the SI unit for acceleration?

Back

m/s²

Front

Why does a car accelerate as it rounds a corner at a constant speed?

Back

Its direction changes.

Front

How is acceleration defined?

Back

Acceleration is the change in velocity of an object divided by the time interval.

Front

In which scenario does a car have no acceleration?

Back

A car with the cruise control set at 80 km/h.

Front

What does negative acceleration indicate?

Back

The object is slowing down.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is uniform acceleration?

Back

Acceleration that is constant over time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What happens to acceleration when an object moves in a circular path at constant speed?

Back

The object experiences acceleration due to the change in direction.

Front

What is the relationship between acceleration and net force?

Back

Acceleration is directly proportional to the net force acting on an object (Newton's Second Law).
