STAAR Test

An image of a toy rocket and forces are shown below. Assuming the only two forces on the toy rocket are lift and gravity, which of the following combinations would result in the rocket moving upward?

• Lift = 5 Newtons and Gravity = 5 Newtons

• Lift = 5 Newtons and Gravity = 4 Newtons

• Lift = 3 Newtons and Gravity = 4 Newtons

• Lift = 4 Newtons and Gravity = 4 Newtons

The diagram shows an investigation in a science classroom. Students pulled the same mass up an inclined plane propped up on five blocks, then six, seven, and eight blocks. Each time, they use a spring scale to measure the forces needed to pull the mass up the inclined plane. This investigation can show how which of the following affects the force needed to move an object up an inclined plane?

• The mass of the object

• The length of the inclined plane

• The height of the inclined plane

• The surface area of the object

When an egg is boiled in a pot of water on the stove, there is more than one kind of heat transfer. Heat is transferred from the stove to the pot directly since they are physically touching. Heat is also transferred from the pot to the egg, carried through the water. What two kinds of heat transfer are represented?

• Stove to Pot = Radiation, Pot to Egg = Conduction

• Stove to Pot = Convection, Pot to Egg = Conduction

• Stove to Pot = Conduction, Pot to Egg = Radiation

• Stove to Pot = Conduction, Pot to Egg = Convection
