Unit 2 Assessment Review

Front

What is the definition of balanced forces?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant velocity.

Front

How can you test the strength of a magnet?

Back

You can test the strength of a magnet by seeing how many paper clips it can attract.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its motion, including its speed and direction.

Front

What is the definition of gravity?

Back

Gravity is the force that attracts two bodies towards each other, pulling everything towards the Earth.

Front

What is the effect of pushing an object?

Back

Pushing an object changes its position and can alter its motion.

Front

How long does it take to walk 300 feet at a normal pace?

Back

It typically takes about 20 minutes to walk 300 feet, depending on the walking speed.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
