What is motion?

Back

Motion is the change in position of an object over time.

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is net force?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude 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 gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.
