Forces & Motion

Front

What are forces that are equal in size, but opposite in direction?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the term for speed and direction?

Back

Velocity is the term that describes both the speed of an object and the direction in which it is moving.

Front

What do we call the combination of all forces acting on an object?

Back

Net force is the total force resulting from the combination of all individual forces acting on an object.

Front

What are forces that cause a change in the motion of an object?

Back

Unbalanced forces are forces that cause a change in the motion of an object, resulting in acceleration or deceleration.

Front

What is the definition of distance traveled per unit of time?

Back

Speed is defined as the distance traveled by an object in a given amount of time.

Front

What is the force that pulls objects toward the Earth?

Back

Gravity is the force that attracts objects toward the center of the Earth.

Front

What is the rate of change of velocity?

Back

Acceleration is the rate at which an object changes its velocity over time.

Front

What is the force that opposes motion between two surfaces in contact?

Back

Friction is the force that resists the sliding motion of two surfaces that are in contact.

Front

What is the term for the total distance traveled divided by the total time taken?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the unit of force in the metric system?

Back

The unit of force in the metric system is the Newton (N).
