Types of Forces
This is the force that pulls objects towards Earth.
What is gravity?
Alonso uses a stretched rubber band to propel a toy car across a flat surface. This force makes the car roll forward.
What is push?
When two equal forces are acting in the opposite direction they are called this.
What is balanced forces?
A force that resists the sliding or rolling of one solid object over another.
What is friction?
Enzo is pushing his brother on a swing. Enzo’s brother says that he wants his feet to go higher. Explain how Enzo could make this happen.
What is push the swing with more force?
When two unequal forces are acting in the opposite direction they are called this.
What is unbalanced forces?
Martin is taking his nephew for a walk in the stroller. This term describes the force that caused the stroller to move forward.
What is push?
Jake is hitting a baseball. The faster he swings the bat, the farther the baseball travels. Explain why.
What is the forward force applied to the baseball is greater?
Explain how a small force can cause a large mass to move.
What is an unbalanced force causes a change in motion?
Phil is standing in front of a chair. The chair is standing on the floor. Phil applies a force to the chair, and it moves on the floor toward him. This force is what Phil applied to do so.
What is pull?
The more force you apply the slower or faster an object will move?
What is faster?
Jack is pulling a rope to the left. Singh is pulling the rope to the right. The rope stays in the same position. Explain how this could be.
What is the two forces are equal and balance each other out?
Two race cars with the same mass started moving on a race track at the same time. One car reached the finish line of the track in 15 sec, and the other reached the finish line in 20 sec. Explain why the cars took different amounts of time to reach the finish line using force.
What is the engine of the faster car exerted more force than the engine of the other car?
How quickly or how far an object moves is directly related to this term.
What is mass?
A rock is balanced on the side of a long, sloping hill. Although the rock is very heavy, a gentle push causes it to start moving down the slope. Explain how this could happen.
What is the forces on the rock were balanced, and a small additional force caused them to be unbalanced?
