Back

created, destroyed

Front

Determine the temperature in Fahrenheit when the Celsius temperature is -10°C.

Back

14°F

Front

What is Newton's First Law?

Back

Front

If Jonny and Patty are pushing against a basketball with equal forces of 20 N on opposite sides, what is the net force?

Back

0 N

Front

An object with a large mass has ____________ inertia and is ______________ to move and stop.

Back

more, harder

Front

What is the definition of inertia?

Back

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

Front

What is the formula for calculating force?

Back

F = ma (Force = mass x acceleration)

Front

What does it mean when forces are balanced?

Back

Balanced forces result in a net force of 0 N, meaning there is no change in motion.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.
