If I am standing on a bathroom scale in an elevator that is freely falling at g=10 m/s^2, then the reading on the scale will be ______ - zero bc of weightlessness. If no external forces are acting on a moving object, it will ______ - continue moving at the same velocity A horse gallops a distance of 15 kilometers in a time of 30 minutes. Its average speed is ____ - 20 km/hr Your pet hamster sits on a record player whose angular speed is constant. If he moves to a point twice as far...

Displacement - distance and direction of an object's change in position from the starting point distance - how far an object moves balanced forces - forces that are equal in size and opposite in direction; they do not move an object and the net force is equal to zero. average speed - total distance divided by total time instantaneous speed - speed at a given point in time unbalanced forces - forces that are unequal in size and the direction is the same; they cause an object to move ve...

Inertia in motion; an object in motion wants to stay in motion in a straight line - momentum What does momentum depend on? - mass and velocity How is momentum related mass and velocity? - directly to both Which has a greater mass- a heavy truck at rest or a a rolling skateboard? Which has greater momentum? - heavy truck; rolling skateboard Is momentum always constant? - yes, if velocity is constant What would make an object's momentum change? - if an object accelerates when a for...

A force is needed to - change an objects state of motion The combination of all forces acting on an object is called the - net force When you hold a rock at rest in your hand, you are pushing upward on it with as much force as Earth's gravity pulls down on it. The net force would be - zero on the rock The scientific unit of force is the newton-- - abbreviated N Tension is a - stretching force Weight is the force of gravity - acting downward on an object A vector is an arrow that - repre...

When you push against a wall with your fingers, they bend because they experience a force. Identify this force? - Opposite force A boxer can't hit a heavy bag with great force. Why can't he hit a piece of tissue paper in midair with the same amount of force? - Doesn't have resistance How many forces are required for an interaction? - Two One end of the rope is pulled with 100 N, while the opposite end is pulled with 100N. The tension in the rope is what? - 100 N A piece of rope is p...

What causes a moving object to keep on course? - Inertia What force exists between objects even in the absence of direct physical contact? - Field Force In the free-body diagram shown above showing a motorcycle, what can you say is happening? - The person is slowing down In the free-body diagram show above, the F N force represents... - The support force of ground on According to Newton's second law, when the same force is applied to two objects of different masses, the lighter mass wil...

1. When does conservation of energy apply? - Always 2. The conservation of energy - ____________ is a fundamental concept of physics along with the conservation of mass and the conservation of momentum. Within some problem domain, the amount of energy remains constant and energy is neither created nor destroyed. 3. A rock is perched at the very edge of the top of a very high cliff ready to fall any minute. What kind of energy does it have? - Potential Energy 4. If the rock isn't moving...

Friction - The force that always opposes motion Coefficient of friction - Force of friction divided by normal force Net force - Resultant force, the sum of all forces acting on an object Free body diagrams - Physical model of a representation of forces acting on a system 2-dimensional motion - Any motion of an object is more than one line, a plane Vector independence - Changes in one vector do not cause changes in another Projectile - Any object launched into the air with no force other th...

B - A cart rolls down inclined track and is accelerating. It fires a ball straight out of the cannon as it moves. What happens to the ball? A.) It falls in front of the cart B.) It falls right back into the cart C.) It falls behind the cart C - You drop a package from a plane flying at constant speed in a straight line. Without air resistance, what will the package do? A.) Remain vertically behind the plane B.) Remain vertically in front on the plane C.) Remain vertically under plane...

What are the steps of the scientific method? - 1. Make an observation/ask a question 2. Form a hypothesis 3. Design and perform an experiment 4. Analyze Data 5. Form conclusion What are Newton's 3 laws of motion? - 1. Law of inertia 2. F=ma 3. For every action there is an equal and opposite reaction What is the net force on a cart pulled with 70 lbs of force to the left and 20 lbs of force to the right? - 50 lbs to the left What does it mean to say something is in mechanical equili...
