IG Phys. Forces, Vector, Newton's law

What can force do to an object?

• Accelerate an object

• Slow down an object

• Have the object remain in place

• Have the object change shape

• All of the above

What is the unit for FORCE?

• N (Newtons)

• lbs (pounds)

• g (grams)

• m/s (meters per second)

This type of force resist motion between two surfaces that are pressed together

• contact
• gravity
• friction

What type of force was at work in the parachute?

• elastic spring force

• frictional force (air resistance)

• magnetic force

• gravitational force

___________ is an opposing force that makes objects in motion slow down.

• force

• speed

• friction

• mass

What will cause an object to move?

• Applied forces
• Balanced forces
• Unbalanced forces

What is the net force?

• 40 N left
• 0 N Balalnced
• 400 N right
• 40 N right

How will this object move? 

• It won't move. 
• It will move to the right. 
• It will move to the left. 
• It will move up. 

The amount of matter in an object is 

• pressure
• weight
• mass
• force

What statement is true?

• Mass never changes. Weight does.

• Weight never changes. Mass does.

• Both mass and weight change because they are affected by gravity.

• Neither mass nor weight change. They are always the same.
