Acceleration Practice

Front

What is acceleration?

Back

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

Front

What is positive acceleration?

Back

Positive acceleration occurs when an object increases its speed.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object decreases its speed.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, experienced by an object moving in a circle.

Front

How do you calculate distance traveled when speed and time are known?

Back

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

Front

What happens to a feather dropped on the moon compared to Earth?

Back

A feather dropped on the moon falls faster than on Earth because there is no air resistance.

Front

What is the unit of acceleration in the metric system?

Back

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

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 uniform acceleration?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration can be calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.
