Force and motion test 1 (O'Melia)

Front

What is air resistance?

Back

A type of friction that occurs when air pushes against a moving object, causing it to negatively accelerate.

Front

How long does it take to travel 10 m if the time is 20 s?

Back

20 seconds.

Front

What two factors does momentum depend on?

Back

Mass and velocity.

Front

What type of force produces a change in motion?

Back

Unbalanced force.

Front

What do you measure when you take the distance traveled at an exact moment?

Back

Instantaneous speed.

Front

What is the definition of 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 the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is balanced force?

Back

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