Forces/Dynamics
The force that is equal and opposite with gravitational force for a stationary object.
What is a normal force?
Displacement divided by time
What is velocity.
Momentum is equal to this.
What is mass times acceleration.
The spring force is equal to this.
What is the spring constant (k) times the displacement of the spring.
This law states that an object will remain in motion unless acted upon by another force.
What is Newtons law of interia or Newton's first law.
This quantity has only magnitude and direction. i.e Velocity.
What is a vector quantity.
Force and time have this relationship in the context of impulse
What is an inverse relationship?
This type of energy is stored energy of an object as a result of it's position.
What is potential energy?
In Newtons second law, the net force is equal to this.
What is mass times acceleration.
The slope of a velocity time graph gives you this graph.
What is an acceleration time graph.
The momentum before a collision will be equal to the momentum after a collision
What is the conservation of momentum?
Mass of an object mulitplied by it's height and gravitational pull is equal to this.
What is the gravitational potential energy.
For every action, there is an equal and opposite reaction.
What is Newton's 3rd law.
When the direction of acceleration and velocity are opposite
What is slowing down?
The area under the line of this kind of graph will be equal to the impulse
What is a Force-Time graph?
A rock is thrown off the edge of a 15.0 m high cliff at a speed of 12.0 m/s. Assume no AR.Determine the landing speed of the rock?
20.9 m/s
A 25 kg mass is pulled across the floor with a horizontal force of 360 N. If its acceleration is 7.11 m/s2 forward, determine the coefficient of friction between the mass and level floor.
What is 0.74 ?
On Planet X, a rock is thrown horizontally at a speed of 29.0 m/s and at a height of 3.20 m. If the rock travels a horizontal distance of 52.0 m, then what is the acceleration due to gravity?
1.99 m/s2 down
How fast does a 2.00 g flea have to be travelling to have the same momentum as a 500 kg vehicle travelling at 90.0 km/h. Answer in standard units.
6.25 x 106 m/s
This law states that the inital momentum of a collision between 2 objects will be same as the final momentum of the collision if there is no external force enacting on the collision.
what is the law of conservation of momentum?
