Which of the following is a unit for acceleration?

• km/s
• m/s²
• mi/hr
• ft

A negative acceleration means that your object is _____. 

• not accelerating
• not moving
• speeding up 
• slowing down 

What are the three ways an object can accelerate?

• Move, change speed, change direction

• Go forward, go backward or stop

• Turn left, turn right or go straight

• distance, displacement or speed

With unbalanced forces, the object will move in the direction of the _______ force.

• equal

• smaller

• larger

What is the net force?

• 17 N Right
• 3 N Right
• 3 N Left
• 17 N Left

If a force causes an object to move, it's considered a(n) __________________ force.

• Balanced
• Unbalanced
• Massive
• Strong

the tendency of an object to resist a change in its motion

• acceleration
• inertia
• mass
• frame of reference

Objects with greater _________ also have greater inertia.

• speed

• mass

• force

• friction

What is the unit of measurement for force?

• m/s

• kg

• N

• g

What is Newton's First Law of Motion?

• F=m x a
• An object at rest stays at rest, an object in motion stays in motion unless acted on by another force.
