Forces: Weight, Electromagnetic

Magnet

• An object that responds to magnetic force

• The sum of all the forces acting on a mass

• The part of a motor that rotates when energy is transferred to it

• The force of gravity on a mass

The standard unit for measuring force in the metric system

• Newton

• Net force

• Spring scale

• Gravity

The force of gravity on a mass

• Weight

• Magnet

• Gravity

• Compress

Gravity

• The natural attraction between masses.

• A change to an object's speed

• A force acting between surfaces in contact.

• To squeeze or press

What is the force acting between any two objects in the known universe all the time?

• Gravitational Force 
• Force of Friction 
• Normal Force 
• Electromagnetic Force 

Imagine you travel to another planets. What will change as you walk around the surface of the planet- your mass or your weight?

• Mass
• Weight 
• Both 
• Neither 

As mass increases, what happens to the gravitational force?

• It increases.
• It decreases.
• It stays the same.
• It acts as a 3rd degree derivative function.

Which of the following will not change in different gravitational fields?

• weight
• force
• mass
• pounds

What is the rate at which Earth's gravity accelerates objects in free fall?

• 9.8 m/s²
• 3.14159 km/hr/s
• 13.7 m/s²
• 42 km/h/s

The main reason a baseball comes down when a boy tosses it up into the air is —

• magnetism is pulling the ball down

• the boy cannot see to catch it

• gravity is pulling down on the ball

• gravity pushes the ball in the air
