4.6D Force and Motion

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, such as iron, and is responsible for the behavior of magnets.

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 is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is a pulling force?

Back

A pulling force is a force that draws an object closer, like pulling a rope.

Front

What is a pushing force?

Back

A pushing force is a force that moves an object away, like pushing a door open.

Front

What is the role of air pressure in motion?

Back

Air pressure can affect how objects move through the air, such as how a balloon rises.

Front

What is the difference between magnetism and gravity?

Back

Magnetism can attract or repel certain materials, while gravity always pulls objects toward each other.

Front

What is the effect of surface texture on friction?

Back

Rough surfaces create more friction, while smooth surfaces create less friction.

Front

How does the angle of a ramp affect the speed of a rolling object?

Back

A steeper ramp usually allows an object to roll down faster due to gravity.

Front

What is an example of a magnetic force?

Back

A magnet sticking to a refrigerator is an example of a magnetic force.
