Force and Motion Vocabulary Practice

A force acting between surfaces as they pass each other causing them to resist motion; friction acts in the opposite direction of an object

• Velocity

• Inertia

• Gravity

• Friction

The measure of the rate an object moves in an amount of time(direction of the object is unknown)

• Force

• Speed

• Acceleration

• Motion

The property of matter that resists changes in motion; if an object is moving, inertia keeps it moving; if an object is stationary, inertia keeps it stationary. The greater the mass, the more inertia an object has.

• Friction

• Inertia

• Velocity

• Gravity

The amount of matter in an object,objects with greater mass are harder to move .

• Speed

• Force

• Velocity

• Mass

The force that pulls objects towards one another

• Momentum

• Gravity

• Acceleration

• Speed

A push or a pull that causes an object to move, stop, or change direction

• Work

• Velocity

• Acceleration

• Force

Imagine there are two object that have the same mass. If you push the first object with more force, will that object move faster or slower than the second object?

• Faster

• Slower

• Same Speed

If you have 2 backpacks and one is empty and the other is full of school books, which one will you have to use more force to carry?

• Empty Backpack

• Full Backpack

Why is a grocery cart harder to push when it is full than when it is empty?

• It is lighter

• It has more wheels

• The cart is old

• The cart has more mass

If an object is sitting at rest, but you want to move it, what must you apply to that object? (could be more than one answer)

• Paint

• Pull

• Push
