What is the force that opposes the motion of two surfaces that are in contact?

Back

Friction is the force that opposes the motion of two surfaces that are in contact.

Front

What principle states that an object in motion will remain in motion unless acted upon by a force?

Back

The principle of inertia states that an object in motion will remain in motion unless acted upon by a force.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, and it is calculated as the mass of the object multiplied by the acceleration due to gravity.

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, causing it to slow down or stop.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula: Force = Mass x Acceleration (F = ma).

What is the effect of gravity on objects in free fall?

Back

In free fall, all objects accelerate towards the Earth at the same rate due to gravity, regardless of their mass.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are in motion.
