Forces and Motion P.1.1 and P.1.2

Front

What is speed?

Back

Speed is the distance traveled per unit of time, usually measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What factors affect friction?

Back

The type of surfaces in contact and the weight of the object affect the amount of friction.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the center of the Earth.

Front

How does gravity affect falling objects?

Back

Gravity causes objects to accelerate towards the ground when they are dropped.

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 mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms (kg).

Front

How does mass affect motion?

Back

More mass means more force is needed to change the object's motion.

Front

What is the relationship between distance and time in motion?

Back

Distance is how far an object travels, and time is how long it takes to travel that distance.
