Physical Science Chapter 2 Vocabulary

Front

Acceleration

Back

The rate of change of velocity of an object which occurs if an object speeds up, changes direction or slows down

Front

Average Speed

Back

The total distance traveled divided by the total time taken.

Front

Balanced Force

Back

When two forces acting on an object are equal in size but act in opposite directions, resulting in no change in motion.

Front

Displacement

Back

Distance and direction of an object's change in position from the starting point.

Front

Distance

Back

How far an object moves.

Front

Force

Back

Push or pull that one body exerts on another.

Front

Inertia

Back

The resistance of any physical object to any change in its velocity.

Front

Instantaneous Speed

Back

The speed of an object at a particular moment in time. Constant for an object moving with constant speed and is different at each point in time for an object that is slowing down or speeding up.

Front

Net Force

Back

The overall force acting on an object when all the individual forces acting on it are combined.

Front

Speed

Back

The distance traveled per unit of time. Calculated by v = d/t, where v = speed, d = distance, and t = time
