• The tendency of an object to resist changes in its motion is called_________?

• Answer: Inertia

• According to Newton’s “third law of motion,” do forces act alone or in pairs?

• Answer: Forces act in pairs. For every “Action force,” there is an opposite and equal “Reaction force!”

• Newton’s “first law of motion,” which states that an object’s motion will stay the same unless it is acted upon by other forces is also called the “Law of _____________.”

• Answer: Inertia

• If we know that the forces acting upon an object are balanced (Net Force = Zero), what do we know about the object’s motion?

• Answer: The object’s motion is staying the same. It’s not changing. It’s not accelerating.

• Using the formula F = m a, what force (in Newtons [N]) is required to accelerate a 100 Kg object 2 m/s2 (meters per second, per second)?

• Answer: 200N

• What is needed to change the direction or speed of an object’s motion? Or, what is needed to get the object to accelerate?

• Answer: Unbalanced forces need to be acting upon it. Put another way, there needs to be a Non-Zero Net Force.

• If one van is loaded with 1 ton of lumber on its roof, and an identical one is loaded with 1 ton of lumber inside its cargo area, which one will be less stable going around a traffic circle and why?

• Answer: The van loaded on its roof will be less stable because of its higher center of mass—it has a higher risk of rolling over.

• In order to calculate the “speed” of an object’s motion, what two things do we need to know?

• Answer: Distance traveled & Time.

• Who was the British scientist that developed the three laws of motion and physics?

• Answer: Sir Isaac Newton

Miss Alanious 300

• If you know the distance an object has traveled, and the amount of time it took, what can you calculate or determine?

• Answer: The object’s speed

• What is the average speed of a person driving 300 miles in 4 hours?

• Answer: 75 miles/h or 75 mph

• The equation for force is __________ & what do the letters stand for?

• Answer: F=M∙A (Force = Mass x Acceleration)
