Gravity

Front

Weight is a force that depends on mass and:
- friction
- gravity
- magnetism
- energy

Back

gravity

Front

Compared to your weight and mass on Earth, if you were on the moon:

Back

Your weight would be less but your mass would remain the same.

Front

Weight of backpack in Newtons? Mass = 10 kg. (g = 9.8 m/s²)

Back

98 N

Front

The picture shows two stacks of books with masses of 3 kg and 6 kg, respectively. How do their weights compare on Earth?

Back

The 6 kg stack has twice the weight of the 3 kg stack.

Front

The picture shows a force vector arrow pointing down. The best name for this downward force is:

Front

The correct equation to solve for weight in Newtons is:

Back

W = mg

Front

Calculate the weight in Newton's of the small stack of textbooks. (Mass = 3 kg; Assume on Earth g = 9.8 m/s²)

Back

29.4 N

Front

On Earth, the acceleration due to gravity is constant. Without air resistance, objects will fall to the ground at the same acceleration.

Back

True

Front

The acceleration due to gravity on Earth is ....

Back

g = 9.8 m/s²

Front

A free-falling object falls at an acceleration of 9 m/s² (with air resistance). How fast is it going after two seconds?

Back

18 m/s
