MFE Vocabulary

What is matter?

• Matter is only found in solid form.
• Matter is the absence of space.
• Matter is anything that has mass and takes up space.
• Matter is a type of energy.

What is mass?

• Mass is the distance between two points.
• Mass is the amount of matter in an object.
• Mass is the speed of an object.
• Mass is a measure of weight.

What is weight?

• Weight is the force of gravity acting on an object's mass.
• Weight is the speed at which an object moves.
• Weight is the measure of an object's volume.
• Weight is the amount of matter in an object.

What is a force?

• A force is a type of energy.
• A force is a unit of distance.
• A force is a push or pull on an object.

• A force is a measurement of temperature.

What is friction?

• Friction is the force that enhances the motion of two surfaces in contact.
• Friction is the energy lost when two surfaces are in motion.
• Friction is the temperature increase caused by two surfaces rubbing together.
• Friction is the force that opposes the relative motion of two surfaces in contact.

What is a balanced force?

• A balanced force is when an object is at rest.
• A balanced force is when the net force acting on an object is zero.
• A balanced force is when forces are acting in the same direction.
• A balanced force is when the net force is greater than zero.

What is an unbalanced force?

• An unbalanced force is a net force that causes an object to accelerate.
• An unbalanced force is a type of friction that slows down moving objects.
• An unbalanced force is a force that acts equally in all directions.
• An unbalanced force is a force that does not change an object's speed.

What is a net force?

• The net force is the total force resulting from the combination of all individual forces acting on an object.
• The net force is the average of all forces acting on an object.
• Net force is the force that opposes motion only.
• The net force is the force applied by a single object.

What is speed?

• Speed is the force applied to an object.
• Speed is the temperature of an object.
• Speed is the distance an object travels in a certain amount of time.

• Speed is the amount of time taken to travel a distance.

What is acceleration?

• Acceleration is the distance traveled over a certain amount time.

• Acceleration is the rate of change of velocity (increasing speed, decreasing speed, changing direction).

• Acceleration is the speed of an object relative to its starting position.

• Acceleration is the force applied to an object that makes it move a certain distance.
