Year 7 Physics Quizziz

What force resists slipping or sliding between two objects?

• Balance

• Friction

• Gravity

• Electromagnetic

Select two examples of contact forces

• Stop

• Go

• Push

• Pull

The north and south poles of two magnets attract

• True

• False

Which force pulls objects toward the center of the Earth?

• Magnetism

• Gravity

• Friction

• Inertia

Which of the following is a non-contact force?

• Friction

• Gravity

• Tension

• Normal

What is weight defined as in physics?

• Matter in an object

• The same as mass

• A force due to gravity on an object

• Gravity

What is mass defined as in physics?

• Gravity acting on an object

• Something very large

• The same as weight

• The amount of matter in an object

Chose the correct answer to describe how the bike in the figure could travel at constant speed.

• Gravity is acting on the cyclist

• The bike in the figure cannot move. It is not accelerating but stationary.

• The driving force is equal to the friction. Not accelerating or decelerating.

• The forces are unbalanced.

What is an example of friction becoming a nuisance?

• Wear and tear on overused parts

• Preventing sliding on a slippery surface

• Breaks in a vehicle prevent an accident

• Resists motion

What do magnetic field lines tell you about the strength of a magnetic field?

• Does not tell us anything about the strength.

• Show the direction that the magnetic force is acting. Close together lines show the magnetic force is strong.

• Show the direction that the magnetic force do not act on.

• Shows the distance between north and south poles
