Think about: the distance the object traveled away from its point of origin.
After a game, she often makes a sketch of the moves that were successful. The dotted line on the sketch shows the direction the ball was moving when she kicked it. The direction if her kick is the solid arrow. How did the motion of the ball change when Mary kicked it?
The ball changed direction and its speed increased.
The ball came to a complete stop.
The ball continued moving in the same direction and its speed increased.
The ball continued moving in the same direction and its speed decreased.
What objects motion would most likely be represented by the graph?

Betty Sue pulls on a box with a force of 18 N to the right. Robert pulls the same box from the opposite side with a force of 20 N to the left. What will be the result?
The box will move up because of the combined force of 38 N.
The box will move to the left because of a net force of 2 N.
The box will move to the right because of a net force of 2 N.
The box will remain at rest.
Sometimes tectonic plates do not move easily passed one another, and the plates become stuck. Forces build up, and when the plates finally move, tension is released, as shown. The sudden movement of the plates is caused by:
The mass of the plates
Unbalanced forces

Centripetal forces

In order to ride a bicycle up a hill with increasing speed---
it is impossible to ride up a hill with increasing speed.
The rider's pedal force must be equal to the friction and the force of gravity.
The rider's pedal force must be greater than friction and the force of gravity.
The rider's pedal force must be less than friction and the force of gravity.
According to Newton't first law (law of intertia) ---
When you drop a tennis ball it will bounce back
when you pull a table cloth out from under dishes the dishes will stay on the table.

A small car and a large semi-truck with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time?
The semi-truck with the larger mass will maintain its velocity while traveling down the hill.
The semi-truck with the larger mass will less inertia than the small car with the smaller mass.
The car with the smaller mass will take longer to stop than the semi-truck with the larger mass.
The car with the smaller mass will require less frictional force (brakes) than the semi-truck with the larger mass in order to stop.
A man hits a pie pan with an egg sitting on top of a toilet paper roll and the egg fell straigt into the cup of water beneath it. Which one of these best explains why the egg fell straight down into the cup instead of staying on the toilet paper roll and pie pan?
Moving the pie pan and toilet paper roll applied an action force to the egg. Since the pie pan was gon, gravity applied a reaction to the egg.
The egg was at rest until the pie pan and toilet paper roll were removed, so it remained at rest in the same location. Once the pie pan was gone, the unbalanced force of gravity caused the egg to fall.
The pie pan and toilet paper roll had less mass than the egg, so a smaller force of gravity acted on the pie pan and toilet paper roll. The larger force of gravity on the egg made it fall.
The acceleration of the egg falling into the cup was equal and opposite to the acceleration of the pie pan and toilet paper roll.
