Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in grams or kilograms.

Front

How does decreasing mass affect the force needed to move an object?

Back

Decreasing mass reduces the force needed to move an object, making it easier to push or pull.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

How does increasing friction affect motion?

Back

Increasing friction makes it harder for objects to slide past each other, slowing them down.

Front

What role does gravity play in motion?

Back

Gravity is a force that pulls objects toward the center of the Earth, affecting their movement.

Front

What happens to an object when it is acted upon by gravity?

Back

An object will accelerate downward towards the Earth when acted upon by gravity.

Front

What is the effect of gravity on a skateboard going down a ramp?

Back

Gravity pulls the skateboard down the ramp, increasing its speed.

Front

How does mass affect the speed of a moving object?

Back

A decrease in mass can lead to an increase in speed, while an increase in mass can slow it down.

Front

What is the relationship between mass and force?

Back

According to Newton's second law, force equals mass times acceleration (F=ma). More mass requires more force to accelerate.

Front

What is an example of increasing friction in sports?

Back

Using sandpaper on a skateboard increases friction, helping the rider maintain grip.
