- 1. Multiple ChoiceWhich statement best explains Newton's Third Law of Motion?An object at rest tends to stay at rest.For every action there is an equal and opposite reaction.The acceleration of an object is based on the force applied.An object continues its motion until an unbalanced force is applied.
- 2. Multiple ChoiceWhich is the best example of Newton's First Law of Motion?a basketball thrown in the air falls to the grounda soccer ball remains motionless until it is kicked by a playera baseball player swings at an approaching ballan ice skater pushes back from a wall and moves backwards
- 3. Multiple ChoiceAn object is resting motionless on a surface. According to Newton's 1st Law, the object will only start to move ifthe net forces on the object equal zeroan unbalanced force is applied to the objectthe upward force of the object is equal to its accelerationtwo forces that are equal and opposite are applied to the object
- 4. Multiple Choice
A truck that is travelling at a constant speed is carrying some boxes. If the truck comes to a sudden stop, what will most likely happen to the boxes?They will stay in the middle of the truck.They will slide toward the front of the truck.They will slide toward the back of the truck.They will fall off the side of the truck. - 5. Multiple ChoiceThe force that draws all objects towards Earth.frictiongravitymassacceleration
- 6. Multiple ChoiceA rubbing together force that slows things down and stops them. It works against motion.accelerationmassgravityfriction
- 7. Multiple ChoiceThe soccer ball is sitting on the half line and Zach runs up to kick it. What law will occur when he kicks it?An object at rest will remain at rest unless acted on by an unbalanced force.An object will remain motionless until it decides to move.The harder Zack kicks the ball, the less distance it will travel.Time travel has always been possible. You just have to believe.

- 17. Multiple ChoiceWhat is the formula for force?F=M/AF=MAF=AXwhat is force?
- 18. Multiple ChoiceAccording to Newton's second law, if you increase the force applied to an object :it accelerates moreit doesn't moveyou get more inertiait decelerates
- 19. Multiple ChoiceHow long will an object remain at rest, according to Newton's First Law of Motion?it can't restuntil noonuntil an unbalanced force occursas long as there are unbalanced forces acting on it
