Physics Vocabulary Quiz

What is a Force?

• The energy of the motion of an object

• The degree of change in the motion of an object

• Something that can enact a change in the motion of an object

• Something that can enact a change in the mass of an object

What is Inertia?

• The tendency of an object to remain at rest.

• The tendency for an object to resist changes in its motion.

• When an object is difficult to slow down.

• The amount of force required to accelerate an object.

What is Mass?

• The total weight an object holds within it.

• The total amount of matter in an object.

• The total amount of inertia an object can receive.

• Where some people go on Sunday.

What is Acceleration?

• The rate at which an object increases in speed.

• The total change in an object's speed over time.

• The rate at which an object moves with respect to time.

• The change in an object's velocity vector over time.

What is Velocity?

• The rate at which an object changes position.

• The speed and direction of an object's inertia.

• The speed and direction of an object's motion.

• The Ferocity of a Velociraptor.

What is a Newton?

• Unit of measurement for Force.

• Unit of measurement for Inertia.

• Unit of measurement for mass.

• Unit of measurement for volume.

What is Friction?

• The heat generated by two objects in relative motion in contact.

• The tendency for an object to try to remain at rest.

• That warm feeling you get when you rub your hands together.

• A force that opposes the relative motion between two surfaces in contact.

What is Momentum?

• Another way of saying velocity.

• The quantity of motion of a moving object.

• How much force an object is carrying.

• Another way of saying Inertia.

What is Equilibrium?

• A state where all forces acting on an object balance out, resulting in zero change of motion.

• A state where all forces acting on an object balance out, resulting in zero motion.

• A state of zero motion, where no forces are acting on an object.

• A state where there are no forces acting on an object, resulting in no motion or change of motion.

What are Newton's 3 Laws of Motion? (There are multiple correct answers [ 3 ])

• A body at rest will remain at rest, a body in motion will remain in motion.

• A force acting on an object is equal to the mass of the object times its acceleration.

• Every action has an equal and opposite reaction.

• All objects have a natural state of motion. Heavier objects are more "lazy" and therefore come to rest faster than light objects. (a feather falls faster than a stone)
