Forces and Motion--5th Grade

Front

What is Inertia?

Back

Inertia is the tendency of an object to remain at rest or in motion unless acted upon by an external force.

Front

What do you need to calculate speed?

Back

To calculate speed, you need to know the distance traveled and the time taken.

Front

What is the force that pulls objects towards the Earth?

Back

The force that pulls objects towards the Earth is called gravity.

Front

How do you describe average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is balanced force?

Back

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

Front

What is unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.
