What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

How does gravity affect falling objects?

Back

Gravity pulls objects toward the center of the Earth, causing them to accelerate downward.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, affecting its acceleration.

Front

What happens to the acceleration of an object when it reaches terminal velocity?

Back

When an object reaches terminal velocity, its acceleration becomes zero as the forces of gravity and air resistance balance each other.

Front

What is the formula for calculating acceleration?

Back

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

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 factors affect the acceleration of an object?

Back

The mass of the object and the net force acting on it affect its acceleration, as described by Newton's second law (F=ma).

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, an increase in mass results in a decrease in acceleration if the force applied remains constant.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.
