Force and Motion

What is a push?

• A push is an action of moving something away from oneself or from its original position.

• A push is a type of computer software

• A push is a type of fruit

• A push is a type of dance move

What is a pull?

• In cooking, a 'pull' refers to the process of removing something from an oven or other hot environment.

• In software development, a 'pull' refers to the action of fetching the latest changes from a remote repository to a local repository.

• In fashion, a 'pull' is a type of sweater that is made from a stretchy material.

• In physics, a 'pull' is the force that acts in the direction of the origin of the force.

What is friction and how does it affect motion?

• Friction is the force that has no effect on the motion of an object.

• Friction is the force that propels the motion of an object and makes it move faster.

• Friction is the force that opposes the motion of an object when it is in contact with another object. It affects motion by slowing down the movement of the object and causing it to eventually come to a stop.

• Friction is the force that causes the object to move in a straight line.

What is gravity and how does it affect motion?

• Gravity is the force that pulls objects sideways. It affects motion by causing objects to move in a circular path.

• Gravity is the force that repels objects away from each other. It affects motion by causing objects to slow down and stop.

• Gravity is the force that attracts objects toward each other. It affects motion by causing objects to accelerate towards the Earth at a rate of 9.8 m/s^2.

• Gravity is the force that has no effect on motion. It only affects objects when they are at rest.

Why do objects fall to the ground when dropped?

• Objects fall to the ground when dropped because they are tired and need a rest.

• Objects fall to the ground when dropped due to the force of gravity.

• Objects fall to the ground when dropped due to the Earth's magnetic pull.

• Objects fall to the ground when dropped because they are afraid of heights.

What is the effect of air resistance on the motion of an object?

• Air resistance has no effect on the motion of an object.

• Air resistance causes the object to move faster.

• Air resistance opposes the motion of an object, slowing it down.

• Air resistance causes the object to move in a circular path.

Why does an object float on water?

• An object floats on water because it is made of a lightweight material.

• An object floats on water due to the force of buoyancy.

• An object floats on water because it is repelled by the water molecules.

• An object floats on water because it is afraid of sinking.
