Forces and Motion Science

Front

What is speed?

Back

Speed is how fast an object changes its position over time, measured as distance divided by time.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

The object will not move at all.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account both magnitude and direction.

Front

What does it mean if forces are balanced?

Back

Balanced forces mean that the net force is zero, resulting in no change in motion.

Front

How is speed different from velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is acceleration?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is inertia?

Back

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

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
