A person weighs 1,470 N on Earth. What is their mass?
F = ma
a = F/m
m = F/a

Acceleration of objects on Earth is always
not enough information
it depends on the object
9.8 m/s2
9.8 N
A sled going down a hill went from 0 to 11 m/s in 8 seconds. What is the acceleration of the sled?
a = Δv/Δt
a = F/m
m = F/a
Δv = initial speed - final speed
A sled accelerating at 2 m/s2 has a mass of 75 kg. How great is the net force acting on the sled?
a = F/m
a = Δv/Δt
F = ma
m = F/a
When calculating a weight for an object on Earth, you need to know mass and
acceleration which is always 9.8 m/s2
if the object is moving
where the object is
how heavy the object is
Mars has a gravitational acceleration equivalent to 0.38g. What does this mean?
If you have a mass you multiply it by 0.38 to get weight on Mars
Mar's gravitational acceleration is 0.38 x 9.8m/s2 = 3.724 m/s2
Mars has a stronger gravitational pull than Earth
A car is accelerating at 8 m/s2 and the force acting on it is 6,000 N. What is the mass of the car?
a = Δv/Δt
a = F/m
m = F/a
Δv = initial speed - final speed
A skateboard at the top of a hill goes from 0 to 8 m/s2 in 7 seconds. What is the acceleration of the skateboard?
a = Δv/Δt
a = F/m
m = F/a
Δv = initial speed - final speed
A person has a mass of 120 kg on Mars which has a surface gravitational acceleration of 0.34 g. What is their weight?
F = ma
a = F/m
m = F/a
not enough information
A rock weighs 200 N on Earth, what is its mass?
F = ma
a = F/m
m = F/a
not enough information
What is the acceleration of a 200 kg rock being pushed on with 800 N?
a = Δv/Δt
a = F/m
m = F/a
Δv = initial speed - final speed
Acceleration is always measured in
m/s2
N
kg
pounds
Weight is a measure of the force of gravity and is always measured in
m/ss
kg
pounds
N
