What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in miles per minute or kilometers per hour.

Front

How do you calculate speed?

Back

Speed = Distance / Time. For example, if you travel 10 miles in 5 minutes, your speed is 10 miles / 5 minutes = 2 mi/min.

Front

What is Net Force?

Back

Net Force is the sum of all forces acting on an object. It determines the object's motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What is the direction of heat transfer?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

What is conduction?

Back

Conduction is the transfer of energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What do molecules in a solid look like?

Back

Molecules in a solid are closely packed together and vibrate in place, maintaining a fixed shape.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.
