You have a box that has a mass of 2g and a box that has a mass of 4g. Which object would require more force to accelerate at a rate of 2 m/s2
The 4g box
What happens to the density of an object when you cut it in half?
A) the density increases
B) the density decreases
C) the density stays the same
C) the density stays the same
A piece of wood has a density of 0.5 g/cm3. Will it sink or float in water which has a density of (1.0g/cm3)?
The wood will float because it is less dense than the water.
You place an arrow in a bull and pull the string of the bow back. Is this an example of kinetic or potential energy?
This is an example of kinetic energy.
When one lightbulb goes off in a series circuit what happesn to the other light bulb?
The other light bulb will also go out.
My dog refuses to leave the park. She has a mass of 25 kg and I want her to accelerate by 5 m/s2. How much force should I pull her with? (Hint: Use Newton's 2nd Law of Motion)
Force = mass x acceleration
Force needed = 125 N
A spoonful of sugar dissolves into a cup of lemonade. Which of the following statements correctly identifies the solute and solvent?
A) Both the sugar and the lemonade are solvents.
B) The lemonade is the solute and the sugar is the solvent.
C) The sugar is the solute and the lemonade is the solvent.
C) The sugar is the solute and the lemonade is the solvent.
You throw a tennis ball which has a density of (0.75 g/cm3) and a baseball which has a density of (2.0 g/cm3) into a pool. Which ball would be more buoyant?
The tennis ball is more buoyant because it is less dense.
Which of the following is a NOT renewable resource?
A) solar
B) biomass
C) hydro electric
D) fossil fuels
D) fossil fuels
When you rub a balloon against a sweater, static electricity causes the balloon to stick to you. What causes static electricity?
Static electricity is caused when electrons move from one object to another and create opposite charges. These opposite charges attract.
You drop a pencil and a golf club off the roof of the school building. Assuming there is no air resistance. Which object will hit the ground first? Why?
They would hit the ground at the same time because all objects fall at the same rate due to gravity.
White light passes through a prism and bends to create a rainbow of colors on the other side. Is this an example of reflection, refraction or transmission?
This is an example of refraction
A rock has a volume of 2 mL and a mass of 6 g. What is the rocks density?
Density = mass / volume
The rock has a desity of 3 g/mL.
What is the law of conservation of energy?
Energy cannot be created or destroyed, only transformed.
Sounds waves are an example of what type of waves? (Hint: does sound exist in space?)
What is a spring scale used to measure?
A spring scale measures force.
