Vocabulary Review 1

On a position-time graph, this would be the "rise"

• Velocity

• Displacement

• Acceleration

• Speed

The slope of this would be zero for an obect moving with constant velocity

• Position-time graph

• Velocity-time graph

• Force-time graph

• Acceleration-time graph

The unit of force

• Newtons

• Kg x m/s

• m/s/s

• Joules

A property of matter related to its tendency to maintain a constant velocity

• Energy

• Inertia

• Force

• Acceleration

What three things can cause objects to move in a circle?

• Friction, gravity or tension

• Tension, work or gravity

• Gravity, energy or momentum

• Friction, momentum or gravity

Work and energy are measured in units of

• Joules

• m/s/s

• Newton's

• kg x m/s

In what type of collisions is kinetic energy lost?

• Inelastic

• Elastic

Momentum is conserved

• only in elastic collisions

• only in inelastic collisions

• in all collisions

On a position-time graph a curved line means the object is

• accelerating

• moving at a constant velocity

• falling due to gravity

• rolling down a hill

A closed, isolated system

• has no work being done to it by external forces

• has work being done to it by external forces

• is where work cannot be measured

• is stored energy
