Abi kicks a soccer ball so hard she falls down. The ball rolls across the sandy beach toward the ocean, but it never makes it into the water. What is the one BEST reason why it may not have made it into the ocean?
the force of the kick was not enough to make it go into the ocean
friction from the sand causes the ball to slow down and eventually stop
gravity causes the ball to slow down and eventually stop
Abi missed kicking the ball
A cannon shoots a cannonball straight off a cliff. The path of the cannonball is shown in the illustration below. Which of the following observations provides the best evidence for the effect of gravity?
The cannonball did not travel in a straight line.
The cannon moved back when the cannonball was fired.
The cannonball was hot when it struck the ground.
The cannon has much greater mass than the cannonball
Two horses are pulling a cart in opposite directions. The cart begins to move in the direction shown. The movement of the cart provides evidence for which of the following?
All horses pull with the same amount of force.
The cart is heavier for Horse 1 than Horse 2.
Horse 2 is pulling with more force than Horse 1.
The wheels on the cart only move in one direction.
In the diagram below, a nail is being removed from the floor with the help of a crowbar. How does the help of the crowbar change the task of removing the nail?
It changes the direction and amount of force needed to remove the nail
It creates much more force by increasing the gravity on the nail
It increases the friction between the nail and the floor
It reduces the amount of air pushing downward on the nail
