Forces, Friction, and Gravity

Front

What is the acceleration due to gravity on Earth?

Back

9.8 m/s²

Front

In the presence of unbalanced forces, an object will move in the direction of which force?

Back

The larger force.

Front

True or False: Your mass on Earth is the same on the Moon.

Back

True.

Front

How do you calculate net force when forces are acting in opposite directions?

Back

You subtract the smaller force from the larger force.

Front

If a hammer and nail are dropped from a building, which one falls faster?

Back

They fall at the same rate.

Front

What is the definition of friction?

Back

Friction is the force that opposes the motion of an object.

Front

What are the two main types of friction?

Back

Static friction and kinetic friction.

Front

What is the formula for calculating weight?

Back

Weight = mass × acceleration due to gravity (W = mg).

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.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their motion and acceleration.
