FORCE & MOTION Vocabulary

Force: choose the correct definition.

• The force that pulls objects to earth. The more mass the more gravity.

• The push or pull on an object with mass causes it to change its velocity

•   Friction is the air that can slow the motion of an object falling through the air.

Motion: Choose the correct definition.

• Friction is the air that can slow the motion of an object falling through the air.

•   The net force is the vector sum of all the forces that act upon an object.

• An object is in motion if its position changes when compared to another object.

Net Force: Choose the correct definition.

• The net force is the vector sum of all the forces that act upon an object.

• The vector is a quantity that has two independent properties, magnitude, and direction.

• The Newton is the standard International SI unit of force.

Unbalanced Force: Choose the correct definition.

• An object is in motion if its position changes when compared to another object.

• Is a place or object used for comparison to determine whether something is in motion?

• Unequal and opposite forces can cause a change in the motion of an object.

Balanced Force: Choose the correct definition.

• Equal and opposite forces cancel each other out.

• Unequal and opposite forces can cause a change in the motion of an object.

• An object is in motion if its position changes when compared to another object

Acceleration: Choose the correct definition.

• Unequal and opposite forces can cause a change in the motion of an object.

• Changing the velocity of an object

• A place or object is used for comparison to determine whether something is in motion.

Speed: Choose the correct definition.

• The distance traveled per unit of time.

• The vector is a quantity that has two independent properties, magnitude, and direction.

• The net force is the vector sum of all the forces that act upon an object.

Velocity: choose the correct definition.

• Is a measure of the amount in an object.

• It is a vector quantity the rate at which an object changes its position.

• The distance travelled per unit of time

Mass: Choose the correct definition.

•    Is a measure of the amount in an object.

   

• The distance traveled per unit of time.

• An object is in motion if its position changes when compared to another object.

Friction: Choose the correct definition.

• Friction is the air that can slow the motion of an object falling through the air.

• The force that is applied in the opposite direction of an object’s movement that can slow the movement of an object.

• Changing the velocity of an object.
