Front

What type of observation is 'The plant grew 10 cm'?

Back

Quantitative observation is a measurement that involves numbers.

Front

What is a correct hypothesis for studying the effect of compost on tomato plant growth?

Back

If tomato plants are grown in soil with compost, then they will grow taller than those grown in regular soil because of the ingredients of the soil.

Front

What are balanced forces?

Back

Balanced forces are opposing forces of the same strength that do not cause a change in motion.

Front

When does a roller coaster have the most potential energy (PE)?

Back

A roller coaster has the most potential energy at the highest point of the track.

Front

What is energy measured in?

Back

Energy is measured in Joules.

Front

Define qualitative observation.

Back

Qualitative observation describes characteristics or qualities that cannot be measured with numbers.

Front

What is a hypothesis?

Back

A hypothesis is a testable statement predicting the relationship between variables.

Front

What is the difference between net force and balanced forces?

Back

Net force is the overall force acting on an object, while balanced forces result in no change in motion.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.
