Forces
What are the units for forces?
What is Newtons?

What is 5 m/s2?
Objects with more mass require ______ force in order to experience the same rate of acceleration.
What is More?
A boy throws a 1.39 kg rock with a force of 10 N. Calculate the rate of acceleration. (Round to the nearest hundredth)
What is 7.2 m/s2?
Which would hit the ground first if dropped from a ladder. Object with a small mass or a large mass?
What is Large mass?
Unbalanced forces result in _____
The net force pushing a 15kg wagon results in an acceleration of 2 m/s2. What is the net force in the wagon?
What is F= 30N?
If given the same force, objects with ____ mass experience a slower acceleration.
What is more?
What is the formula for calculating weight?
What is W= m x g?
Which would change on the moon? Mass or weight? Why?
What is weight?
Weight is mass x gravity.
True or false: Objects experiencing balanced forces are at rest.
What is False?
What is the amount of force required to accelerate a 20kg object to 30 m/s2?
What is F= 600N?
In order to accelerate at the same rate, objects with ______ mass require less force.
What is less?
A net force of 15N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s2. Determine the mass of the encyclopedia.
What is M = 3.0kg?
Toy car 1 is pushed with a 30N of force, then the same car is pushed with 50N of force. Which amount of force will cause the fastest acceleration?
What is 50N?
What force opposes gravity?
What is normal force?
An abject with a mass of 1500 g accelerates for 10.00 m/s2 when force is applied. What is the magnitude of the force?
What is F= 1500 N?
Objects with more mass would experience ____?
What is acceleration if given the same force (compared to as smaller mass)?
Suppose that sled is accelerating at a rate of 2 m/s2. If the mey force is tripled and the mass is doubled, then what is the new acceleration of the sled?
What is 3 m/s/s?
The original value of 2 /m/s/s must be multiplied by 3 (since A and F are directly proportional) and divided by 2 (since A and M are inversely proportional?
With unbalanced forces, the object will move in the direction that the _____ force is being applied.
What is Larger/stronger?
Which would hit the ground first if dropped: Bowling ball or tennis ball?
What is Neither, they would fall at the same rate of acceleration due to gravity?
Calculate the mass of a falling object if it hits the ground with a force of 24N.
What is 2.45 kg
which variables in this equation have an inverse relationship?
F=ma
What is Acceleration and mass?
Suppose that a sled is accelerating at a rate of 2m/s2. If the net force is tripled and the ma is halved then what is the new acceleration of the sled?
What is 12 m/s/s?
The original value of 3 m/s/s must be multiplied by 3 (since a and F are directly proportional) and divided by 1/2 (since A and M are inversely proportional)
A cart is being moved by a constant net force. you place a bag of dog food in the cart, and now the mass of the cart has doubled. How has the acceleration changed?
What is Acceleration has halved if mass is doubled?
