What causes the ballon to move?

• an object in motion stays in motion

• action reaction

• law of force and acceleration

• air moves forward the balloon moves forward 

What type of motion would describe the car pictured below?

• speed

• velocity

• acceleration

What is the motion of the object from 0-2 seconds?

• the object is at rest

• the object moves at a constant speed

• the car is accelerating

• the car is decelerating 

What is the motion of the object from 6-7 seconds?

• the object is at rest

• the object moves at a constant speed

• the car is accelerating

• the car is decelerating 

What is the motion of the object from 7-8 seconds?

• the object is at rest

• the object moves at a constant speed

• the car is accelerating

• the car is decelerating 

If both carts have the same mass, what will happen if student A pulls on the rope?

• both will move

• only A will move

• only B will move

• neither will move 

Both are standing still on their roller blades. What happens when the girl pushes the boy from behind?

• the girl and the boy will both move forward

• the boy will move forward and the girl will stand still

• the boy will move forward and the girl will move back ward

Assume a 32.53 kg ice skater is on a nearly frictionless surface. What force would be needed to accelerate the skater a 4m/s²?

• 130.12 N

• 13.012 N

• 13012 N

• 1301.2 N

When sitting in the car, driving forward, the driver suddenly stops, what happens to the passenger?

• the passenger moves fowards

• the passenger moves back 

• the passenger remains as was

How will the acceleration of Cart A differ from Cart B?

• Cart A will accelerate faster because it has more mass

• Cart B will accelerate faster because it has less mass

• Both will accelerate equally because mass does not affect acceleration
