Final Question

What causes a change in motion?

What causes a change in motion?

A Force

Does a magnet exert a force?

Yes

Does a force have to have magnitude and direction?

Yes

The rocket force that increases velocity is known as?

Thrust

A force that decreases the velocity of an object as it moves through air is called??

Drag

Momentum is found by multiplying the ----and-----of an object

Mass and velocity

What are two kinds of momentum?

Linear momentum and angular momentum

What scientific principle states that momentum is conserved?

The law of conservation of momentum

Why do bowlers put a spin on a ball?

To increase momentum (rotational + linear)

What is the momentum equation?

p=mv

What is kinetic energy defined as?

It is known as work needed to accelerate an object from original velocity to current velocity.

What is the kinetic energy equation?

(1/2)mv squared

When energy is stored within an object what is it called?

Potential energy

Is a compressed spring an example of potential or kinetic energy?

Potential energy

How is energy created and destroyed?

Energy cannot be created or destroyed

What is the difference between kinematics and dynamics?

Kinematics describes motion and dynamics describes the causes of motion

What is velocity?

Speed with direction

What is a vector that describes the difference in the position between two points?

Displacement

What is the difference between distance and displacement?

Distance is the path the object took where displacement is the least amount of space from the objects starting point to the objects end point

Does projectile motion involve constant acceleration?

Yes

Is gravity one of the fundamental interactions seen on earth?

Yes

How can the gravity of the moon be observed on earth?

The formation of tides

The weight of an object is equal to the ---- exerted onto the object by gravity.

Force

On earth is the acceleration due to gravity constant?

Yes the gravity is constant

Is an objects weight proportional to its mass?

Yes they are directly proportional
