Net Force
A cyclist was traveling against the wind at 32 km/hr2 and had a mass of 27.5 kg. What was the net force applied to the bike?
880N
What is the first step of Design Thinking?
Empthaize
What is the prefix of k?
kilo-
What is the unit for seconds?
Force
Force is an action that can change motion. It is a push or a pull.
A new test rocket was launched from a local field. The rocket had a mass of 528 kg and accelerated at 37.9 m/s2. What was the force exerted by the rocket as it traveled through the air?
19,975 N
What is the second step of Design Thinking?
Define
What is the prefix of m (10^-3)?
milli-
What is the unit for acceleration?
m/s/s, m/s^2
Kinematics
It describes the motions of points, bodies, and systems of bodies without considering the forces that cause them to move.
A hockey player was practicing for an upcoming game and asked his coach to record his average acceleration when hitting the hockey puck. The player exerts an force on the hockey puck, causing it to accelerate at 117.5 m/s2. The hockey puck has a mass of 170 g. What is the hockey puck's net force when hit?
20 N
What is the third step of Design Thinking?
Ideate
What is the prefix of n?
nano-
What is the unit for Force?
N
Density
Is the amount of mass in a volume, units
A skier races downhill at a rate of 1.7 m/s2, but came in second place. The competitor who came in first had a mass of 52 kg. If both skiers were recorded going the same acceleration, how much net force did the first place skier exert in the competition?
88 N
What is the fourth step of Design Thinking?
Prototype
What is the prefix of g?
giga-
What is the unit for Net Force?
F
Buyancy
A child was playing catch with their dog where they would throw a ball, and the dog would catch it in its mouth. The mass of the ball thrown was 0.058 kg. The ball accelerated at 3.5 m/s2 towards the dog. What is the net force, to the nearest Newtons, that accelerates the ball?
0.2N
What is the fifth step of Design Thinking?
Test
What is the prefix of μ?
micro-
What is the unit coefficient of friction?
μ
Terminal Velocity
The maximum speed of a falling object can't fall any faster because the air friction cancels out the force of gravity.
