| Imagine a box on a ramp. If the forces on the box are balanced the box ______ move. | will not |
| If a rocket is traveling through space at a ________ speed, then ______ must be applied to the rocket in order to change its direction or speed. | constant and force |
| If a ball is rolled down an inclined plane at different angles, what is true about the speed of the ball as the angle between the inclined plane and the ground is increased? | It will roll faster. |
| The school bus is driving through the city taking students to school. The bus crosses one city block every 10 seconds. If all the city blocks are the same length, then you can say that the motion of the bus is_________. | at a constant speed |
| A toy rocket is fired up into the air and a parachute deploys at the highest point on its path. The rocket takes twice as long to make it back to the ground as it did to reach it highest point. It takes the rocket longer to fall back to the ground due to | air resistances |
| If the same force is applied to a submarine, a cheetah, a hummingbird, and a school bus then the ___ will have its motion changed the least. | submarine |
| If the same force is applied to a submarine, a cheetah, a hummingbird, and a school bus then the ________will have its motion changed the most. | hummingbird |
| If the speed at which different parachutes fall under different weights is modeled the _______ should be kept the same during the testing of the model. | height of the fall |
| A student wants to go faster down the playground slide. He should _____ friction by spraying the slide with ___ to speed up. | decrease and water |
| There are 3 ropes securely attached to a ball that is resting on the ground. If three people pulled on the ropes with the same amount of force then the ball will most likely move in a | straight pattern |
| In order to win a game of tug of war ____ | a person has to pull at a greater force than the other person |
| A boy is helping his music teacher move her piano. _________ to cause the piano to move. | For friction to be overcome, you must have enough force |
| A sailboat moving through the water experience a force of 2500 newtons exerted by the wind on its sails. The water & air resistance apply a force of 1500 newtons in the opposite direction of the boat's direction of travel. This means___ | the forces are unbalanced in the direction of motion |
| A student throws a ball across a field. The two forces acting on the ball are | force and gravity |
| When a car turns its tired while in motion, ___ is the force that pulls the car in a new direction. | friction |
| If the same force is applied to a bowling ball, pencil, car, and train engine then the __ will be the MOST LIKELY to move. | pencil |
| If the same force is applied to a bowling b all, pencil, car and train engine then the ___ will be the LEAST likely to move. | train engine |
| NASA sent a space probe carried by a rocket into space. The space probe was released from the rocket when it reached outer space. Newton's___ law BEST describes the motion of space probe after it was released by the rocket. | FIRST |
| A science class built four model rockets. The rocket with the ___ weights in grams, will go the highest. | least |
| Two teams are playing tug-of-war. With both teams pulling on opposite ends of the rope, neither team can pull the other toward them because the forces are ______. | balanced |
