Force & Motion 7.7 ABCD modified

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is velocity?

Back

The speed of an object in a specific direction, e.g., 20 m/s north.

Front

What is acceleration?

Back

The rate at which an object's velocity changes over time.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Forces that are not equal and can cause an object to accelerate or change direction.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the unit of force?

Back

Newton (N).

Front

What is gravitational force?

Back

The force of attraction between two masses, such as the Earth and an object.
