Front

What is the average speed of an object that travels 90 m in 9 seconds?

Back

10 m/s

Front

What is the relationship between speed, distance, and time?

Back

Speed is equal to distance divided by time.

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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the effect of net force on an object at rest?

Back

If the net force acting on an object at rest is zero, the object will remain at rest.

Front

How does increasing mass affect the force required to accelerate an object?

Back

Increasing mass requires a greater force to achieve the same acceleration, according to Newton's second law (F = ma).
