Forces and Motion - Test 5th

What is force?

• changing directions

• moving from one place to another

• push or pull on an object

• motion

What is motion?

• change in position of an object

• force

• gravity

• push or pull on an object

What is friction?

• the force that pulls things together

• the force that slows moving things down

• a force that can push or pull certain metal objects

• push or pull on an object

What is gravity?

• a force that pulls things together

• push or pull on an object

• a force that pushes things apart

• a force that can push or pull certain metal objects

What is magnetism?

• a force that slows moving things down

• a force that can push or pull certain metal objects

• a force that pulls things together

• a force that can only push on wooden objects

What does the force of gravity do?

• Push

• Pull

• Push and Pull

• Slide

What does speed measure?

• direction

• velocity

• mass

• how fast an object moves over a given period of time

What must happen for work to be done?

• the object must create a force

• The object must be magnetic

• The object must move

• The object must produce power

What is the formula to calculate work?

• Force x Speed = Work

• Speed x Velocity = Power

• Force x Power = Work

• Force x Distance = Work

Work is measured in

• newtons

• joules

• watts

• electrons
