1D Motion
What is magnitude and direction?
What is projectile motion?
What is any object that is thrown?
What is Newton's first law?
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
Why do cars have airbags?
What is to increase the time of impact?
What is work?
the energy transferred to or from an object via the application of force along a displacement.
What is the SI unit for acceleration?
What is m/s2?
What is the only force acting on a projectile?
What is gravity?
What is Newton's second law?
the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
An object has a mass of 100 kg moving at 5 m/s. What is the linear momentum of the object?
What is 500?
What is the formula for force?
W=Fs
W = F.d
W = (Fcos θ)d
What is the difference between speed and velocity?
What is speed is a scalar and velocity is a vector?
How many motions does a projectile have?
What is two motions?
What is newtons third law?
For every action there is an equal and opposite reaction.
A stunt person jumps from the roof of a tall building, but no injury occurs because the person lands on a large, air-filled bag. Which one of the following BEST describes why no injury occurs?
What is longer time of impact?
What is energy?
ability to do work, which is the ability to exert a force causing displacement of an object.
What makes displacement different from distance
What is magnitude and direction?
What are the two 2 types of projectile motion?
What is vertical projectile motion and horizontal projectile motion?
What is Newton's second law called?
What are Newton's 3 laws called?
The law of momentum
The law of inertia
A golf club has 10 kg m/s of momentum when it hits a golf ball that is at rest. After the collision, the golf club has a momentum of 1 kg m/s and the golf ball has a momentum of 9 kg m/s. Which of the following comparisons is TRUE about the change in momentum of the two objects?
What is equal and opposite change in momentum?
What is power?
the rate at which work is done.
If an object has a constant velocity, what can be said about its acceleration?
What is the acceleration is 0?
What are the 3 main concepts of projectile motion?
What is range, symmetry, and maximum height?
A man is whirling a 0.5 kg ball on a 1.0 m long string at 2 m/s. What is true about the force on the ball?
What is tangent to the circle?
A layer of padding is added to car dashboards because it can reduce some injuries during a collision. How does the padded dashboard make people safer?
What is increasing time of impact?
What are the 3 equations for power?
P = Et
P = Wt
P = V2R
