force gravity friction

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is friction?

Back

A force that opposes the motion of an object when it is in contact with another surface.

Front

What is the formula for calculating acceleration?

Back

Acceleration = Force / Mass.

Front

What two factors determine the strength of gravitational force?

Back

Mass and distance.

Front

What is mass?

Back

The amount of matter in an object, measured in kilograms.

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as Weight = Mass x Gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².

Front

How does increasing mass affect acceleration if force is constant?

Back

Increasing mass decreases acceleration.

Front

What happens to friction when surfaces are rougher?

Back

Friction increases with rougher surfaces.
