Question | Answer |
---|---|
Who established the laws of motion we use today? | Sir Isaac Newton. |
How many basic laws of motion are there? | 3. |
What is Newton's Second Law? | Newton's second law states that the force of an object is directly proportionate to it's acceleration. |
What is the formula used to find force? | FORCE = MASS * ACCELERATIONORF=ma |
If an object's mass and acceleration are adjusted so that they are still proportionate to the orginal, will the force still be proportionate? | Yes. |
If a toy car's acceleration is increased, and the mass is the same, will the force be greater or less? | Greater. |
A remote control car has a mass of 50 grams and is accelerating at a rate of 3m/s/s. What is the force | 150 Newtons |
What is the definitoin of a Newton | Newton- The newton is the unit of force in the SI system; it is equal to the amount of force required to accelerate a mass of one kilogram at a rate of one meter per second per second |
Define the variables in the equation F=ma | F= Force of the objectm= Mass of the objecta= Acceleration of the object |
A toy car has a mass 0f 100g and a force of 200 Newtons. What is the acceleration? | 2m/s/s |
