Gravity Mass Weight
What is Earth's Gravitational pull?
9.8 m/s
Gravitational, Pushing, etc
What is not true about Newton's first law
An object in/out of motion will always stay that way
A 4kg object accelerates at 4 m/s. What is the force?
What is the gravitational force of the moon
1.62 m/s
What is F?
Net force acting upon an object
Example of unbalanced force
Someone kicking a still object such as a rock
A force of 10 N is applied to an object with a mass of 4kg what is the acceleration?
2.5 m/s
How does a planets mass affect its gravitational pull
What is air friction?
The force from air molecules pushing against something
Example of balanced force
A ball rolling down a hill
What is the mass of an object that weighs 10 N on earth which has a gravitational force of 9.8 m/s
1.02 kg
What is a difference between mass and weight
Mass doesn't change with gravity; weight does
If a net force is constant will a change in mass affect the acceleration
What is Newton's 2nd Law?
Acceleration of an object depends on its mass and the amount of force applied
How much does a 28 kg person weigh on the moon which has a gravitational force of 1.62 m/s ?
17.28 kg
