Force and Motion

The change of position over time is called

• position
• speed
• motion
• location

An object is ___________________ if its position changes relative to another object.

• in motion
• a frame of reference
• at rest
• magical

A force can best be defined as:

• A property of an object
• A push or pull in a particular direction
• Yoda's best friend
• A push or a pull

What is Newton's 1st Law:

• F=ma
• for every action, there is an equal and opposite reaction
• mass multiplied by velocity
• an object in motion stays in motion unless acted upon by an unbalanced force

What is the net force?
←      →
7N    10N

• 7N to the left
• 17N to the right
• 10N to the right
• 3N to the right

If there is no change in speed, direction, or shape, forces can be described as...

• unbalanced
• balanced
• unfair
• net force of 5N to the right

An unbalanced force can be defined as:

• a net force of 0 (zero)
• no change in speed, direction, or shape
• a change in speed, direction, or shape
• bad news for a car if it is trying to stop in an emergence

______________ is the ability to cause change.

• energy
• friction
• force
• motion

Energy due to motion is _________________ energy.

• potential
• force
• kinetic
• friction

The faster an object moves, the ________ kinetic energy it has.

• more
• less
• none of the above
• all of the above
