Forces and Gravity Test

_________________is the force which resists or opposes motion between two touching surfaces. This force goes in the opposite direction.

• Electric

• Friction

• Gravity

• Speed

Which below is the unit for weight?

• Kilogram

• M/S

• Net force

• Newtons

Planets in our Solar System each have varying amounts of gravity. If an astronaut were to travel from Earth to Jupiter, which factor would change depending on the amount of gravity present?

• Mass

• Velocity

• Speed

• Weight

An object in motion will stay in motion unless an external force acted on it. This is an example of

• First law of motion

• Second law of motion

• Third low of motion

For every action there is and equal and opposite reaction.

• First low of motion

• Second Law of motion

• Third law of motion

• Newtons universal gravitation law

The greater the mass of and object, the greater the amount of force that is needed to accelerate it. This is the

• Newton's firsts law

• Newton's second law

• Newton's third law

A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them.

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
