Amplify Force/Motion EOM Review 23-24

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.

Front

How does friction affect movement?

Back

Friction makes movement of an object harder by opposing its direction of motion.

Front

What happens to friction on a rough surface?

Back

Friction increases when an item moves on a rough surface.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces. It can be zero if forces are balanced.

Front

What is mass measured in?

Back

Mass is measured in grams.

Front

How does mass change on the moon compared to Earth?

Back

Your mass remains unchanged on the moon; it is the weight that changes due to different gravitational forces.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravity.

Front

What is mechanical advantage?

Back

Mechanical advantage is the factor by which a machine multiplies the force put into it, making work easier.

Front

What is the effect of friction on mechanical advantage?

Back

Friction reduces mechanical advantage by requiring more force to overcome it.

Front

What is the unit of force?

Back

The unit of force is Newtons (N).
