Physical Science Final Review

Front

What is acceleration?

Back

Acceleration is the change in velocity of an object divided by the time interval.

Front

What is the formula for momentum?

Back

The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is an interaction pair in physics?

Back

An interaction pair consists of two forces that are equal in size and opposite in direction, such as the foot and the face when a kick occurs.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does it mean if an object is in motion?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating average speed?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the law of conservation of momentum?

Back

The law of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.
