Force and Motion

Front

A push or pull on an object

Back

force

Answer explanation

A push or pull on an object is defined as a force. Force is a vector quantity that causes an object to accelerate, making it the correct choice among the options provided.

Front

a change in an object's position

Back

motion

Answer explanation

Motion refers to a change in an object's position over time. Unlike speed, which measures how fast something moves, or friction and inertia, motion specifically describes the act of changing location.

Front

A force that attracts things to Earth.

Back

gravity

Answer explanation

The force that attracts objects towards Earth is known as gravity. It is responsible for keeping us grounded and is distinct from other concepts like force, inertia, and motion.

Front

What is an example of Push motion?

Back

Hammering a nail into a piece of wood.

Answer explanation

Hammering a nail into wood is a clear example of push motion, as it involves applying force to drive the nail into the surface. The other options involve lifting or pulling actions, not pushing.

Front

An object at rest can be changed by? Options: A push or pull, Temperature, Weight, Location

Back

A push or pull

Answer explanation

An object at rest can be changed by a push or pull, which applies a force to it, causing it to move. Temperature, weight, and location do not directly cause a change in motion.

Front

What is an example of Pull motion?

Back

Removing a plug.

Answer explanation

Removing a plug is a clear example of pull motion, as it involves exerting force to draw the plug out of its socket. In contrast, kicking, walking with a cart, and typing do not involve pulling actions.

Front

Shooting a basket and kicking a football are examples of?

Back

a push

Answer explanation

Shooting a basket and kicking a football both involve applying force to an object, which is an example of a push. This force propels the ball towards the target, demonstrating the concept of a push in physical activities.

Front

Brushing your hair and putting on a pair of socks are examples of?

Back

a pull

Answer explanation

Brushing your hair and putting on socks involve pulling actions. When you brush your hair, you pull the brush through your hair, and when you put on socks, you pull them onto your feet. Thus, they are examples of a pull.

Front

The tendency of an object to resist a change in its motion - an object in motion will stay in motion

Back

inertia

Answer explanation

The correct answer is inertia, which describes an object's tendency to resist changes in its motion. This means an object in motion will remain in motion unless acted upon by an external force.

Front

What is the tendency of an object to resist a change in motion?

Back

inertia

Answer explanation

The tendency of an object to resist a change in motion is known as inertia. It describes how objects remain at rest or in uniform motion unless acted upon by an external force, making inertia the correct answer.
