Question | Answer |
---|---|
Can cause a resting object to move, or it can accelerate a moving object by changing the objects speed or direction. | Force |
The overall force acting on an object on an object after all the forces are combined. | Net Force |
The friction force that acts on objects that are not moving. | Static Friction |
A force that opposes the direction of motion of an object as it slides over a surface. | Sliding Friction |
The friction force tht acts on rolling objects. | Rolling Friction |
The force that opposes the motion of an object through a fluid. | Fluid Friction |
The constant velocity of a falling object when the force of air resistance equals the force of gravity. | Terminal Velocity |
The motion of a falling object (projectile) after it is given an initial forward velocity. | Projectile Motion |
A force that acts between any two masses. | Gravity |
Fluid friction acting on an object moving through the air. | Air Resistance |
The product of an object's mass and its velocity. | Momentum |
Associated with charged particles. | Electromagnetic Force |
An attracting force that acts between any two masses. | Gravitational Force |
A center-directed force that continuously changes the direction of an object to make it move in a circle. | Centripetal Force |
