Physics Chapter 2: Force & Motion

How is gravity affected by mass?

• the larger the mass of the object, the greater the gravity
• small objects have no gravity
• gravity is not affected by mass of objects, whether large or small

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

If these boys are pulling with the same amount of force.  What will happen?

• The boy in blue will win.
• They will not move at all.
• The boy in red will win.
• Both will fall down.

What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

The tendency of an object to stay in motion or at rest is called 

• velocity
• acceleration
• speed
• inertia

Work involves all of these except 

• force
• movement
• distance
• time

When two children of equal weight sit at opposite ends of a seesaw, they create

• gravity
• unbalanced forces
• motion
• balanced forces
