What is the definition of force?

• Force is a measure of an object's temperature.

• Force is the mass of an object multiplied by its acceleration.

• Force is the energy required to lift an object.

• Force is an interaction that causes an object to change its Speed.

How does motion relate to position?

• Position is fixed and does not change with motion.

• Motion is the same as position.

• Motion only occurs in a straight line.

• Motion is the change in position of an object over time.

What is a reference point in motion?

• A reference point is the distance traveled by an object.

• A reference point is a fixed location used to measure the position and motion of an object.

• A reference point is a type of force acting on an object.

• A reference point is a moving object used to track speed.

How can you determine if an object is in motion?

• An object is in motion if it is spinning in place.

• An object is in motion if it is stationary relative to a reference point.

• An object is in motion if it is vibrating without changing position.

• An object is in motion if its position changes relative to a reference point.

How does the speed of an object relate to its motion?

• The speed of an object determines how quickly it moves through space.

• Speed has no effect on motion.

• An object moves faster when it is heavier.

• Speed is only relevant in a vacuum.
