Friction can be described as a:
non-contact force
contact force
slowing of motion
rough surface
Choose the BEST answer that describes how the mass of an object affects its motion.
The greater the mass of an object, the slower the motion of the object.
The greater the mass of an object, the faster the motion of the object.
The greater the mass of an object, the greater the force to move the object.
The greater the mass of an object, the greater the distance the object will travel.
Melissa and Gabe were testing the flight of leaves as they tossed them in the air. The leaves would go up and then came to a rest on the ground. What force made the leaves land on the ground?
gravity
friction
air pressure
mass

change speed
change directions
object at rest will move or change positions.

The 5th graders were playing a game of tug-of-war. The class was divided equally with half the class on one side of the rope and the other half on the opposite side. For 5 minutes the students pulled and pulled but neither side could pull the flag to one side or the other. Choose the description of the forces during the 5th grade tug-of-war.
The forces were unbalanced in the game.
The forces were friction, gravity, and chemical energy.
The students all had the same amount of strength.
The forces were balanced in the game.
What happens when 2 equal forces act on an object in opposing directions?
no movement; won't move
Object will move in the direction of the force
Object will move in the opposite direction of the force
the object flies
What is a contact force?
A force that touches the object to make it move or change directions
force that does not touch the object to make it move or change direction.
What is a non-contact force?
A force that touches the object to make it move or change directions
force that does not touch the object to make it move or change direction.

A boy throws a baseball up in the air. Why does the baseball fall back down to the ground?
the mass of the baseball decreases, causing it to fall
the weight of the ball causes the ball to fall
the force of gravity causes the ball to fall
the density of the ball causes the ball to fall
When we talk about gravity, 'down' just means ___
towards the North Pole
away from the South Pole
away from the Earth
toward the Earth
"Gravity pulls things down to Earth", really means that gravity pulls things ___
toward the South Pole.
toward the Earth.
away from the North Pole.
toward Antarctica.
An apple falls to the ground because –
the force of gravity pulls it out into space.
of the magnetic forces acting on the apple.

the force of gravity pulls it towards Earth's center.
What force pulls everything toward the ground, including you?
gravity
friction
elasticity
electrical force
