Forces and Motion Concepts

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is an opposing force?

Back

An opposing force is a force that acts in the opposite direction to another force, affecting the motion of an object.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal, causing a change in motion, such as acceleration or deceleration.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can be an increase or decrease in speed.

Front

What is deceleration?

Back

Deceleration is a decrease in speed or a negative acceleration.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and motion?

Back

The greater the mass of an object, the more force is needed to change its motion.
