Kinematics
What is the formula for calculating velocity (vf) if you know initial velocity (vi), acceleration (a), and time (t)?
vf = vi + at
What is the condition for an object to be in static equilibrium?
The sum of all forces is zero. It's velocity is zero.
What is the formula for Newton's second law of motion?
F = ma
What is Newton's First Law of Motion?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
If an object is launched at an angle of 62 degrees with the horizontal and has an initial velocity of 16 m/s, what is the horizontal component of velocity? (Round to the nearest integer)
8 m/s
Calculate the displacement (s) of an object with an initial velocity of 10 m/s, an acceleration of -2 m/s^2, and a time of 5 seconds.
-25 meters
Calculate the tension in a horizontal rope supporting a 1000 N object in equilibrium.
1000 N
Calculate the force required to accelerate a 500 kg car at 4 m/s2.
2000 N
According to Newton's Second Law, how is force related to acceleration and mass?
F = ma (Force is directly proportional to mass and directly proportional to acceleration).
Calculate the time of flight for a projectile launched at an angle of 30 degrees with an initial velocity of 15 m/s.
3.09 seconds
If an object is moving with a constant velocity of 8 m/s, how far will it travel in 12 seconds?
96 meters
A 200 N box is placed on an inclined plane with an angle of 30 degrees. Calculate the normal force acting on the box.
100 N
If a 10 N force is applied to a 2 kg object, what will be its acceleration?
5 m/s²
What is Newton's Third Law of Motion?
For every action, there is an equal and opposite reaction.
What is the "trajectory" of an object experiencing 2-D projectile motion?
The path the object takes.
A car accelerates from rest at a rate of 3 m/s2. How long will it take to reach a speed of 30 m/s?
10 seconds
*Use your reference tables*
If a 300 N force is applied horizontally to move a 200 kg crate on a rough surface, and the crate doesn't move, calculate the coefficient of static friction.
0.6
Calculate the gravitational force acting on a 75 kg astronaut if they are on a planet with 3 times the gravity we have on Earth.
What is their weight?
Fg = 2205 N
Weight = 2205 N
Explain why a seatbelt is important in terms of Newton's First Law.
A seatbelt prevents the passenger from continuing to move forward when the car suddenly stops.
Ties the passenger's inertia to the car's inertia.
A ball is kicked horizontally off a cliff with a velocity of 15 m/s. How long will it take to hit the ground below?
1.53 seconds
If an object falls freely from rest and hits the ground after 4 seconds, what is the acceleration due to gravity (g)?
9.8 m/s²
A man is 1.5 meters tall. He is standing on a scale and leaning against the wall. The scale reads 70 N. If the the man is in equilibrium and makes an angle of 60 degrees with the ground, calculate the force the scale exerts on the man.
70 N
If a 2000 kg truck accelerates from rest to 20 m/s in 10 seconds, what is the net force applied?
4000 N
Give an example of an everyday situation where Newton's Third Law is demonstrated. Label the action and reaction.
ie. Jumping off a diving board (action) pushes the board down (reaction).
If a projectile is launched with an initial velocity of 30 m/s at an angle of 60 degrees with the horizontal, calculate the maximum height it reaches.
45 meters
