Forces, Friction, and Gravity

What is a force?

• A force is a type of sound

• A force is a push or pull.

• A force is a type of energy

• A force is a form of matter

Name two types of forces.

• Gravitational forces and electromagnetic forces

• Push forces and pull forces

• Frictional forces and tension forces

• Contact forces and non-contact forces

What is frictional force?

• Frictional force is the force that causes objects to float

• Frictional force is the force that attracts objects to each other

• Frictional force is the force that accelerates the motion of an object

• Frictional force is the force that opposes the motion of an object when it is in contact with another object or surface.

How does friction affect the motion of an object?

• Friction only affects the direction of motion

• Friction affects the motion of an object by creating resistance and slowing it down.

• Friction increases the speed of an object

• Friction has no effect on the motion of an object

What is gravity?

• Gravity is the force that causes objects to float in space.

• Gravity is the force by which objects are pushed away from a planet or other body.

• Gravity is the force by which a planet or other body draws objects toward its center.

• Gravity is the force that pulls objects toward the sun.

What is the effect of gravity on Earth?

• The effect of gravity on Earth is to make objects float in the air.

• The effect of gravity on Earth is to pull objects towards the center of the planet.

• The effect of gravity on Earth is to push objects away from the center of the planet.

• The effect of gravity on Earth is to cause objects to move sideways.

What is the difference between weight and mass?

• Weight is the amount of matter in an object, while mass is the force exerted on an object due to gravity

• Mass is measured in pounds, while weight is measured in kilograms

• Weight and mass are the same thing

• Weight is the force exerted on an object due to gravity, while mass is the amount of matter in an object.

How does gravity on Earth compare to gravity on the moon?

• Gravity on Earth is only stronger than gravity on the moon at certain times.

• Gravity on Earth is weaker than gravity on the moon.

• Gravity on Earth and the moon is the same.

• Gravity on Earth is stronger than gravity on the moon.

What is the effect of gravity on other planets?

• The effect of gravity on other planets varies depending on their mass and size.

• All planets experience the same level of gravity

• Gravity has no effect on other planets

• Gravity on other planets is stronger than on Earth

How does the force of gravity on Jupiter compare to the force of gravity on Earth?

• The force of gravity on Jupiter is about 2.5 times stronger than the force of gravity on Earth.

• The force of gravity on Jupiter is about 0.5 times stronger than the force of gravity on Earth.

• The force of gravity on Jupiter is about 10 times stronger than the force of gravity on Earth.

• The force of gravity on Jupiter is about the same as the force of gravity on Earth.
