Kinematics
This is the value that can be found from the area under a velocity-time graph.
What is displacement?
This is the acceleration at the very top point on the path of a projectile.
What is 9.8 m/s/s?
The principle of physics that states forces always come in pairs that are equal in magnitude and opposite in direction.
What is Newton's Third Law?
This is the direction of the tension in a string when you twirl a ball in a circle above your head.
What is toward the center?
Attractive force existing between all objects with mass.
What is force gravity?
This is reached when an object falling through air is no longer accelerating.
What is terminal velocity?
This angle produces the maximum range of a projectile.
What is 45 degrees?
This is the type of picture that can (should) be drawn for any dynamics problem.
What is a free-body diagram?
The gravitational force changes by this much if you increase the distance between two planets by 3 times.
What is 1/9?
A skier was gliding downhill at 15 m/s. How long did it take her to ski the 630 m to the base of the hill?
What is 42s?
This is the distance that a ball released from rest will fall during the 2nd second if it traveled distance H during the first second.
What is 3H?
A rugby player attempts a kick after scoring a try. The ball was kicked at an angle of 55 degrees with an initial resultant velocity of 18 m/s. The initial horizontal velocity is ___.
17.1m/s
This is the direction that kinetic friction acts on an object.
What is opposite of the motion?
The ratio of the force the Earth exerts on the moon to the force the moon exerts on the Earth.
What is one?
A stone is dropped into a deep well and is heard to hit the water 3.41 s after being dropped.
How deep is the well?
What is 57 m?
This is the type of acceleration that an object must have in order to be able to use the top three equations on your equation sheet.
What is constant?
A projectile is launched at an angle of 30o above the horizontal. The initial velocity is 35 m/s and it is in the air for 3.0 s. Determine the max height of the projectile.
2. 16 m
The normal force on a 10 kg block on a horizontal surface that has a string pulling straight up on it with a tension of 48 N.
What is 50 N?
A car traveling at a constant speed is going around a circle with a radius of 70 meters. It takes 120 seconds to travel around the circle one time. Determine the car's velocity.
What is 3.66 m/s?
An orienteer runs north at 5 m/s for 120 seconds, and then west at 4 m/s for 180 seconds. Determine the length of the resultant displacement vector.
What is 937 m?
This is how long it will take a 5 kg object to hit the ground if dropped from rest at a height of 12.5 m. You can ignore air resistance.
What is 1.60 seconds?
A long jumper leaps with an initial horizontal velocity of 9.5 m/s at an angle of 40° to the horizontal.
Calculate how far they jump.
What is 9 m?
This is the normal force on a 10 kg object that rests on an incline that makes a 25 degree angle with the horizontal.
What is 90.6 N?
A 72 kg skateboarder is moving down a ramp with a 6.0 m radius. At the bottom of this ramp he reaches a speed of 6.5 m/s. Determine the normal force acting on the skate.
What is 507 N?
This is the law that describes the speed of the planets as they orbit the sun.
