Newton's Laws
Jane pushes a cart with a mass of 12kg at an acceleration of 4 m/s2. Joey pushes a cart with a mass of 18kg at with the same acceleration.
Newton's 2nd law
Taylor lives 400 miles away from her dad. It takes her 6.25 hours to get to his house. What is Taylor's average speed?
64 mi/hr
Gravity exerts this on an object causing objects to fall.
Force
A marble sits atop a ramp. As the marble begins to move down the ramp, where does the kinetic energy come from?
Gravity
A semitrailer is is going down a steep grade at 11 m/s. If the the semitrailer's speed increases to 33 m/s, how much more kinetic energy is produced before crashing into a tree?
9 times more energy
A marble rolls down a ramp and strikes a stationary plastic cube, causing the cube to move.
Newton's 1st law
A cheetah can run 32 m/s. How far can a cheetah run in 12 seconds?
384 meters
It's the amount of gravitational force applied to an object
Weight
Where is the greatest amount of kinetic energy as a marble moves down a ramp?
At the bottom of the ramp
An SUV traveling at 22 m/s producing 2,700 kj of kinetic energy. How much energy would be produced by a car that is 3 times smaller?
8,100 kj
A basketball player dribbles a ball. The ball bounces off the floor and back to the players hand.
Newton's 3rd law
A car driving at 11 m/s speeds up to 25 m/s in 7 seconds. What is the car's acceleration?
2 m/s2
It's the accepted value of acceleration for gravity on Earth.
9.8 m/s2
A marble travels down ramp and strikes a plastic cube sitting at the end of the ramp. What happens to the marble's kinetic energy?
It is transferred to the cube.
A car driving 12 m/s produces 675 kj of energy. If you double the speed, how much energy will it produce?
2,700 kj
In billiards, cue ball is hit with a stick, causing the ball to move forward.
Newton's 1st law
Jane pushes a 12kg cart at an acceleration of 4m/s2. How much force does Jane use to push the cart?
48N
If a tennis ball and a ping pong ball are dropped from the same distance at the same time, which ball will hit the ground first?
They will both hit at the same time
A marble rolls down a ramp. Where is its potential energy equal to its kinetic energy?
In the middle of the ramp
Your sports car is going 22 m/s on the freeway and hits a deer releasing 900 kj of energy. How much energy is produced if you are driving your sports car at 66 m/s?
8,100 kj
In billiards, a cue ball is hit with the stick causing the ball to move. The cue ball strikes another ball causing the balls to travel in equal and opposite directions.
Newton's 1st and 3rd laws
Joey pushes a boulder with a force of 16N. This causes the boulder to roll from it's initial speed of 2 m/s to 10 m/s in 4 seconds. What is the mass of the boulder?
8kg
Air resistance
A marble rolls down a ramp and strikes a cube causing the cube to move. The cube stops moving. What happened to the cube's kinetic energy?
It is transferred to thermal energy
You're driving a in a residential area at 11 m/s in your sports car and producing 225 kj of energy. How much energy would be produced if you were driving an SUV that is 5 times the size of your car at the same speed?
1,125 kj
