Week 15 Flashcard 8th

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. All objects with mass have inertia.

Front

What does it mean for an object to be 'at rest'?

Back

An object is 'at rest' when it is not moving and remains in the same position over time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the formula for velocity?

Back

Velocity = Speed + direction.

Front

What does Newton's first law state about objects in motion?

Back

Objects will move at the same speed and direction unless a force acts on them to change that motion.

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 an object in motion if no net force acts on it?

Back

If no net force acts on an object in motion, it will continue to move at a constant speed in a straight line.

Front

What is a net force?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it indicates the path along which an object is moving, making velocity a vector quantity.
