Anything that has mass and takes up space.

Back

Matter: The substance of which any physical object is composed.

Front

Which force holds us to earth's surface?

Back

Gravity: The force that attracts a body toward the center of the earth, or toward any other physical body having mass.

Front

Which force acts on an object by touching the object?

Back

Friction: A force that opposes the motion of an object in contact with a surface.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What is inertia?

Back

Inertia: The tendency of an object to resist changes in its state of motion.

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 acceleration?

Back

Acceleration: The rate of change of velocity of an object.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N): The unit of force that causes a 1 kg mass to accelerate at 1 m/s².
