How to answer the picture questions
Two cars are on ramps. Car A is at the bottom. Car B is at the top. Which car will move because of gravity?
Car B will move because gravity is a pulling force, so car B will be pulled down the ramp toward Earth. Car A is already at the bottom of the ramp, so gravity will not pull it down any further.
A cat pushes a flower vase off a shelf. What will happen to the vase?
The vase will fall to the floor because gravity is pulling it down toward Earth. Once the cat pushes the vase off the shelf, there is nothing left to stop gravity from pulling it down.
A boy pushes a tire to the left. Which two forces are being exerted on the tire?
A push and a touching force. The arrow points the same way the boy is pushing — to the left.
Why does an apple fall from a tree? Use science words.
The apple falls from the tree because of the force of gravity. Gravity attracts objects toward Earth. Forces act between two objects. Earth is the object that exerted a force on the apple. Gravity is a non-touching force, so it acts without Earth touching the apple.
