A person running is an example of

• Potential Energy

• Friction

• Kinetic

• Resistance

Pulling back a sling shot but not letting go is an example of

• Kinetic energy

• friction

• speed

• potential energy

rubbing your hands together quickly is an example of

• speed

• friction

• potential energy

• force

If an equal force acts on each of the following objects, which will have the greatest acceleration (speed)?

• golf ball

• soccer ball

• football

• baseball

Which of the following is NOT a force?

• Newton

• gravity

• magnetism

• friction

Newton's first law of motion states that an object's motion will not change

• a force continues to be applied

• the object has no acceleration

• acted upon by another force

• a large mass

If two arm wrestlers exert a force on each other’s hands, and the hands don’t move, the forces must be ______________________.

• unbalanced

• weak

• balanced

• strong

The first law of motion says that an object at rest will remain at rest unless

• it continues in a straight line

• a nearby star acts on it

• an outside force acts on it

• it is placed on a flat surface

According to the third law of motion, for every action there is ….

• a force sending it backward

• an equal and opposite reaction

• a greater force pushing on it

• a movement in all directions

A pull or push that acts on an object is called a(n)

• force

• acceleration

• speed

• gravity
