Motion and Forces Quiz

What is motion?

• Motion is when an object's distance from another object is changing.

• Motion is when an object remains stationary.

• Motion is when an object changes color.

• Motion is when an object increases in size.

What is a frame of reference?

• A frame is a perspective from which you observe and measure movement.

• A frame is a physical structure that holds objects.

• A frame is the wood that surrounds a painting.

• A frame is a unit of time.

What is an inertial reference frame?

• An inertial reference frame is when you are observing the motion of an object that is located on another object with a constant velocity.

• An inertial reference frame is a stationary point in space.

• An inertial reference frame is where you observe motion internally.

• An inertial reference frame is a theory of time.

How do we measure motion?

• By using a reference point to measure the distance an object moves in a certain amount of time.

• By counting the number of steps an object takes.

• By measuring the relative change in weight of an object.

• By observing the object's reference frame.

What is displacement?

• Displacement is the difference between an object's starting point and ending point.

• Displacement is the total distance traveled by an object.

• Displacement is the speed of an object.

• Displacement is the reference direction of an object.

How do you calculate speed?

• Speed = Distance/Time

• Speed = Time/Distance

• Speed = Distance × Time

• Speed = Distance + Time

What is a force?

• A force is when one object pushes or pulls on another object.

• A force is a type of energy.

• A force is a unit of time.

• A force is a magical energy that binds the universe.

What is a contact force?

• A contact force is when one object exerts a force on another object while they are touching.

• A contact force is when no molecules are touching.

• A contact force is a only happens between solid objects.

• A contact force is a change in momentum.
