Gravity Review

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. It is what keeps us on the ground and causes objects to fall.

Front

Which object has the strongest gravitational pull?

Back

The Sun has the strongest gravitational pull compared to Earth and Mars.

Front

What is drafting in sports?

Back

Drafting is a technique where an athlete or car races behind someone else to reduce air resistance.

Front

What is friction?

Back

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

Front

What affects the strength of gravity on an object?

Back

The strength of gravity on an object depends on its mass (how big it is).

Front

True or False: Our weight on Earth is due to the force of gravity.

Back

True.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against objects moving through the air.

Front

How does mass affect gravity?

Back

The more mass an object has, the stronger its gravitational pull.

Front

What is the relationship between gravity and weight?

Back

Weight is the measure of the force of gravity acting on an object.

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 on that mass.
