Contact and Non-Contact Forces

Front

What are the poles of a magnet called?

Back

North and South Pole.

Front

What is the difference between MASS and WEIGHT?

Back

Mass DOES NOT change if the force of gravity changes. Weight DOES change if the force of gravity changes.

Front

Magnetic Force is an example of ____________ force.

Back

non-contact.

Front

What is a NON-CONTACT force?

Back

A push or pull force where the objects are not touching.

Front

Why do planets orbit the Sun?

Back

The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.

Front

What is a CONTACT force?

Back

A push or pull force where the objects are touching.

Front

What is gravitational force?

Back

A force that attracts two bodies towards each other, proportional to their masses.

Front

What is friction?

Back

A contact force that opposes the motion of an object.

Front

What is the formula for weight?

Back

Weight = Mass x Gravitational Acceleration (W = m x g).

Front

What is the role of gravity in our solar system?

Back

Gravity keeps planets in orbit around the Sun.
