Forces And Motion

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What does a higher force of friction indicate?

Back

A higher force of friction indicates that a surface has more stopping power, making it harder for objects to slide over it.

Front

Which surface has the most friction: aluminum, glass, chromium, or titanium cadmium alloy?

Back

Titanium cadmium alloy has the most friction.

Front

What force causes objects to come to a stop?

Back

Friction is the force that causes objects to come to a stop.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it has.

Front

If two objects are at rest, which one has the least inertia?

Back

The object with the least mass has the least inertia.

Front

What happens to a car's velocity when it is going at a constant speed?

Back

When a car is going at a constant speed, its velocity remains the same over time.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

How does weight change on different planets?

Back

Your weight would be different on different planets due to varying gravitational forces.

Front

What is the formula for calculating weight?

Back

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