100
A ball rolling down a steep ramp and continuing up another ramp that follows, rather than stopping at the bottom of the first ramp, is an example of this.
What is Newton's 1st Law?
100
A crate weighing 25 kg is pushed with a force of 5 Newtons. Calculate the acceleration of the crate.
What is 0.2 m/s^2?
100
This is the kind of force that slows a train, and creates heat and sparks from the contact between train wheels and the rails on which the wheels follow whenever the brakes are applied.
What is friction?
100
A cyclist applies his brakes suddenly to avoid hitting an obstacle in the middle of a biking trail.
The cyclist will fly over the handlebars, due to his inertia.
200
Jet aircraft often have multiple engines or thrusters, resulting in greater force and thus higher speed--an example of this law.
What is Newton's 2nd Law?
200
An RC airplane accelerates at 4.2 m/s^2, with a mass of 1.13 kg. Calculate the force of its takeoff, rounded to the nearest hundredth.
What is 4.75 N?
200
All objects in the universe have varying amounts of this, depending on their mass.
What is gravity?
200
For the hundredth time, Charlie Brown attempts to kick Lucy's football "to the moon," but she pulls the ball away from him at the last second. And this happens...
Due to the inertia of the kick, Charlie Brown flies into the air, and lands flat on his back.
300
A catapult takes advantage of this law to launch projectiles at opposing armies in medieval Europe.
What is Newton's 1st Law?
300
The F-16 Fighting Falcon has a maximum takeoff weight of 188000 N. Calculate its mass, rounded to the nearest tenth.
What is 19183.7 kg?
300
In the equation "Force = mass X acceleration," the number 9.8 can be subbed in for one of these three variables when finding vertical acceleration.
What is acceleration?
300
A baseball is hit out of Great American Ball Park, and lands in the river. Explain what happens to the water around the splashdown point.
The normal force of the water will slow the ball's descent, according to Newton's 3rd law.
400
The unintended kicking-back of deck cannons aboard British warships, during the American Revolution, were a prime example of the effect of this law in action.
What is Newton's 3rd Law?
400
A car weighs 450 kg, and has an acceleration of 3.4 m/s^2. Calculate the force of its acceleration.
What is 1530 N?
400
While your weight would change if you were weighed on Jupiter, only your ___ would stay consistent.
What is mass?
400
One train engine pulls a freight car forward with a force of 20 N, while another train pulls in the opposite direction with a balanced force. What would happen if the first train was joined by a weaker engine with a quarter of the force?
The freight car will begin to move in the direction of the first train's pull.
500
Friction is caused between the rails of train tracks and the wheels of a locomotive, causing the deceleration that displays this law.
What is Newton's 2nd Law?
500
A stage spotlight falls from its attachment point with a force of 3.6 N. Calculate its mass, rounded to the nearest tenth.
What is 35.3 kg
500
A more common measurement unit of force, 0.225 Newtons are equal to one of these.
What is a pound?
500
A skydiver's parachute is released from its backpack. What will happen to the descent of the skydiver?
The skydiver's descent will slow, as air resistance becomes an opposing force to the weight of the skydiver, decreasing overall force (Newton's 2nd Law).
