Acceleration is a rate of change in

P= mv the p stands for

__is the force that opposes the sliding motion of two surfaces that are touching

A push or pull

Every action there is an equal and opposite reaction is

An object's property that resists change in motion

Newton's first law is also known as the law of

A real car moving at 10 km/hr has more momentum than a toy car moving at the same rate because

As the skydiver falls to the earth what force besides gravity is playing a factor?

The product of friction is

The relationship among mass, force, and acceleration is explained by

If an object is at rest the forces acting on the object are

The net force directed toward the center of a circular path

The state of equality of momentum

The amount of matter of an object

What method do we use to solve word problems?

A change in an objects position

What is the net force of an object that has 10 N of force applied in both direction?

The acceleration due to gravity is

F=ma

The acceleration of an object toward the center of a circular path

What is the formula to find weight?

When finding forces if the arrow point in opposite direction what do you do with the values?

A moving object property that is related to how much force is needed to change its motion

The gravitational force exerted on an object

The definition of velocity is

Fill the blank on the test will be

An object at rest

In the absence of air, a feather and a hammer that are dropped at same height + time they will

What net force is required to accelerate a car at a rate of 2 m/s² if the cars mass is 1000kg?

A rocket taking off

Your stomach dropping on a roller coaster

A group of objects exerts forces only on each other, then the total momentum does not change
