What is the attractive force between two objects that depends on their masses and the distance between them?

Back

Gravitational force.

Front

What is the formula for calculating gravitational potential energy?

Back

GPE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What type of graph is best for displaying data in percentages?

Back

Pie Chart.

Front

How do you convert kilograms to grams?

Back

Front

What is the formula for calculating work done?

Back

Work = Force x Distance.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object.

Front

What is centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².
